There is a congressional district in California where the median household income is $182,000 - the highest of any district in the United States. They work at Apple, Google, Meta, and hundreds of startups. They drive Teslas. Their children attend some of the best public schools in America.
They also vote 68% Democratic. Their representative co-chaired Bernie Sanders' presidential campaign. He supports Medicare for All and the Green New Deal. His Heritage Action score is 0% - he votes against conservative positions on every issue Heritage tracks. He is now building a $13.4 million war chest for a 2028 presidential run.
The district is CA-17. The representative is Ro Khanna. And the reason this matters is not Khanna himself - it is what his district tells us about the political future of the United States.
CA-17 is 57% Asian and 20% Caucasian - the most Asian congressional district in the country. Sixty-three percent of its households speak a non-English language at home. Two-thirds of its tech workers are foreign-born. In 1970, the county at the heart of this district was 82% Caucasian. In a single lifetime, the founding population went from a dominant majority to a 28% minority.
And the political result is a district that is wealthier than anywhere else in America and more progressive than Manhattan.
The Transformation
Santa Clara County - the heart of Silicon Valley and the geographic core of CA-17 - has undergone the most dramatic demographic transformation of any major county in the United States.
| Year | Caucasian | Asian | Hispanic |
|---|---|---|---|
| 1970 | 82% | 3% | 13% |
| 1990 | 59% | 17% | 20% |
| 2000 | 46% | 24% | 23% |
| 2010 | 37% | 30% | 26% |
| 2024 | 28% | 39% | 25% |
Asians are now the largest racial group in the county, surpassing Caucasians who have dropped from 82% to 28% in 54 years. The Indian-born population alone is 148,000, or 8% of the county. That counts only foreign-born - the total Indian American population including all generations is far higher. In Cupertino, 22.6% of residents are Indian American. In Fremont, 18%. In Sunnyvale, 15.5%.
San Jose, the largest city in Silicon Valley, went from 75.7% Caucasian in 1970 to 28.7% Caucasian by 2010. That is a 47-point drop in 40 years.
The mechanism is the H-1B visa program. In 1990, 30% of Silicon Valley tech workers were foreign-born. By 2025, that number is 66%. Of those, 23% are from India and 18% from China. Only 17% were born in California.
The tech industry didn't just import workers. It imported an electorate.
Who Is Ro Khanna
Rohit Khanna was born in Philadelphia in 1976 to parents who immigrated from Punjab, India in 1968. His maternal grandfather, Amarnath Vidyalankar, was an Indian independence movement politician who spent two years in prison pursuing independence from Britain. Khanna studied economics at the University of Chicago and law at Yale. Obama appointed him Deputy Assistant Secretary of Commerce in 2009. He has represented CA-17 since 2017.
His political record:
- Co-chaired Bernie Sanders' 2020 presidential campaign. Not endorsed - co-chaired.
- Supports Medicare for All. Has publicly stated the U.S. "should be moving toward Medicare for All."
- Early backer of the Green New Deal. Supported the concept before AOC was sworn in. Took the No Fossil Fuel Money Pledge.
- Co-sponsored the College for All Act with Sanders. Free public college funded by a Wall Street speculation tax.
- Co-introduced legislation with Sanders to cancel all medical debt.
- Heritage Action Scorecard: 0%. Votes against conservative positions on every issue Heritage tracks.
- GovTrack ranks him the 67th most left-wing member of the House.
- Member of the Congressional Progressive Caucus. Endorsed by Justice Democrats - the organization that recruited AOC.
On immigration, Khanna celebrates America as "a magnet for the world's talent." He supports broad legal immigration, opposes restrictions on H-1B pathways, and has called Trump's immigration enforcement "anti-immigrant."
This is not a moderate Democrat who happens to represent a wealthy district. This is one of the most progressive members of Congress, representing the richest district in the country. His ideological commitments are indistinguishable from Bernie Sanders'.
2028
Khanna is actively positioning for a 2028 presidential run. He has visited New Hampshire and traveled to swing states. He has amassed a $13.4 million war chest, raising $3.6 million in Q1 2025 alone. If AOC runs for Senate instead of president, Khanna will likely dominate the progressive lane.
A son of Indian immigrants. Representing a majority-Asian district created by immigration policy. Running for president on Medicare for All, the Green New Deal, and expanded immigration. This is what the political pipeline looks like when demographic transformation reaches critical mass.
The District That Shouldn't Be Progressive
Here is the paradox that exposes the real dynamic.
CA-17's median household income is $182,000. These are not downtrodden workers demanding redistribution. These are engineers making $200,000 at Google. They live in houses worth $1.5 million. Their children attend excellent schools. By every economic measure, they should be the most conservative voters in America.
Instead, they vote 68% Democratic and elect a man whose political hero is Bernie Sanders.
The progressive voting pattern in immigrant-heavy districts is not driven by economics. It is driven by identity. The majority of residents are first or second-generation immigrants. Their primary political identity is not "taxpayer" or "homeowner" - it is "immigrant." The Democratic Party has positioned itself as the party of immigration.
The data supports this at scale:
- Every 1-percentage-point increase in a district's non-citizen adult population corresponds to a 1.8-point increase in Democratic vote share.
- 20 of the 24 congressional districts where one in five adults is a non-citizen were won by a Democrat in 2022.
- All Asian-majority congressional districts in the United States elect Democrats.
- All 15 of America's wealthiest congressional districts elected Democrats in 2024. The one near-exception - NY-3 on Long Island - is predominantly Caucasian and voted for Trump 51-47.
The correlation between wealth and conservatism has reversed. The wealthiest, most immigrant-heavy districts now vote far to the left. The poorer, more native-born districts vote to the right.
Democrats now represent 79 of America's 100 wealthiest congressional districts, up from 50 a decade ago. This did not happen because wealthy Americans became socialists. It happened because wealthy districts are now disproportionately populated by immigrant communities that vote Democratic regardless of income.
The 95,000 Who Don't Matter
In the 2024 general election, Anita Chen (R) received 82,415 votes in CA-17. Roughly 95,000 registered Republicans live in the district. These are tech workers, engineers, small business owners, and professionals who vote conservative. Their votes have zero impact on their representation.
In a D+21 district, the Republican candidate cannot win. The primary is the general election, and the primary is decided by the Democratic base. A conservative tech worker in Cupertino has less political representation than a voter in a swing district making a third of their income.
This is the structural consequence of demographic transformation. Once a district crosses a demographic threshold, the political outcome is locked in. Community organizations, media, cultural institutions, and social pressure all orient in one direction. Conservative voices in Silicon Valley describe being "undercover." The chair of Santa Clara County's Republican Party has said: "It's easier to be gay than it is to be conservative in Silicon Valley."
Google employees gave Hillary Clinton's campaign $1.56 million in 2016. Of 74,000 Alphabet employees, only 39 contributed to Trump's campaign.
How It Happened: The H-1B Pipeline
The demographic transformation of Silicon Valley was not organic. It was engineered through immigration policy - specifically, the H-1B visa program created by the Immigration Act of 1990.
In 1990, 30% of Silicon Valley tech workers were foreign-born. By 1993, 23% of foreign-born engineers in the Bay Area were from India. 87% of Indians working in Silicon Valley had arrived only since 1970. The H-1B program provided the legal framework for tech companies to import workers at scale.
Today, 66% of Silicon Valley tech workers are foreign-born. The top source countries are India (23%) and China (18%). The program processes 400,000 petitions annually, far beyond its original intent of filling genuine skill gaps.
The pipeline works in stages. A company sponsors a worker. The worker arrives on a temporary visa. The company sponsors them for a green card. After five years, they become citizens. They petition for family members. The chain migration multiplier - documented in our chain migration analysis - kicks in.
One H-1B worker becomes an entire family through chain migration. The family settles in an ethnic enclave that grows into a voting bloc. The bloc elects representatives who support more immigration. The cycle reinforces itself.
Santa Clara County did not go from 3% Asian to 39% Asian by accident. Immigration policy - the H-1B visa, chain migration, and the Diversity Visa - produced this outcome. The tech companies got cheaper labor. The Democratic Party got a permanent electoral majority. The founding population of Silicon Valley got replaced.
What 82% to 28% Looks Like
When the Caucasian population of a county drops from 82% to 28% in a single lifetime, the consequences extend beyond elections.
Language: 63% of households in CA-17 speak a non-English language at home. The most common are Chinese (16.7% of households), Spanish (10.9%), and Hindi (5.5%). English is technically still the majority language, but large portions of daily life - commerce, worship, media consumption, social interaction - occur in other languages.
Cultural institutions: Temples, gurdwaras, and mosques have joined or replaced churches as the dominant houses of worship. The cultural calendar includes Diwali, Lunar New Year, and Eid alongside Christmas and Easter. The cultural landscape of Silicon Valley is more similar to Singapore or Dubai than to the American town it was in 1970.
Political priorities: The issues that dominate CA-17 politics - H-1B expansion, family reunification, climate policy - reflect a population whose primary identity is tied to immigration status and progressive social values. Traditional American political concerns - gun rights, religious liberty, border security - are not just minority positions. They are culturally alien.
This is not a failure of the individual immigrants who live in Silicon Valley. Most are hardworking, educated, and law-abiding. The failure is systemic. When immigration policy transforms a community so rapidly that the original population becomes a small minority, assimilation stops. American culture is replaced by a cosmopolitan, globalized culture with no particular attachment to American traditions or American identity.
Who Did This Benefit?
The standard defense of mass immigration into Silicon Valley is that it fueled innovation, built world-class companies, and grew the economy. All of that may be true. But it raises a question that almost nobody in Washington is willing to ask: who actually benefited?
The tech companies benefited. They got access to a massive labor pool willing to work long hours on visa-dependent terms. An H-1B worker cannot easily switch employers, cannot negotiate from strength, and knows that losing the job means leaving the country. This is not a free labor market. It is a captive one. It suppresses wages for American-born engineers while generating enormous profits for shareholders and executives.
The immigrants themselves benefited. They moved from countries with lower wages and fewer opportunities to one of the richest labor markets on earth. That is entirely rational. Nobody faults an individual for seeking a better life.
The ultra-wealthy benefited. Venture capitalists, tech founders, and major shareholders saw their companies scale on labor that cost less than a domestic workforce would have demanded. The wealth generated in Silicon Valley over the past 35 years has been extraordinary. It went overwhelmingly to the top.
But what about the Americans who were already there?
Santa Clara County in 1970 was a comfortable, middle-class place. Families bought homes on single incomes. Neighborhoods were safe and familiar. Schools taught in English. A young couple starting out could afford to live where they grew up. That community is gone. Not because of a natural disaster or an economic collapse - because immigration policy decided that the needs of Apple, Google, and the global labor market mattered more than the people who already lived there.
The median home price in Santa Clara County is now $1.6 million. The median household income in CA-17 is $182,000 - and even at that level, housing is a struggle. For anyone earning less, the area is simply unaffordable. Teachers, firefighters, nurses, small business owners - the people who made Silicon Valley a functioning community - have been priced out entirely. Many have left California altogether.
This is the part of the story that never gets told. Immigration advocates point to GDP growth and innovation. They do not mention that the Americans who built that community before the transformation cannot afford to live in it anymore. They do not mention that an entire generation of Californians has been displaced from their own neighborhoods. They do not ask whether any of this was supposed to happen.
The purpose of immigration policy is supposed to be the benefit of the American people. Not the benefit of multinational corporations. Not the benefit of foreign nationals. Not the benefit of political parties seeking new voters. The American people. If an immigration system transforms a livable, affordable American community into one of the most expensive places on earth - a place where the founding population has been reduced to 28% and the average family cannot buy a home - then that system has failed the people it was supposed to serve.
The question Americans should be asking is simple: why are we allowing this? Why is it considered acceptable that immigration policy has made entire regions of the country unlivable for the people who were born there? Why does the conversation about immigration always center on what it does for employers and immigrants, and never on what it does to the communities that absorb the change?
Silicon Valley is the answer to what happens when nobody asks those questions for 35 years.
The National Pattern
CA-17 is the most extreme case, but it is not unique. The same dynamic is playing out across the country, at varying stages of completion.
The research is consistent across every dataset:
- Immigrant communities vote as blocs, not as individuals, until assimilation occurs - and assimilation requires time, pressure, and reduced numbers (as documented in our elections analysis)
- The fiscal cost of immigrant-heavy communities falls on state and local taxpayers regardless of income level (as documented in our fiscal analysis)
- Concentrated immigrant settlement delays assimilation and creates parallel institutions (as documented in our Putnam research analysis)
What Silicon Valley shows is that even the best-case immigration scenario - highly educated, high-income, employed immigrants - produces the same political outcome. The progressive voting pattern is not a function of poverty or dependence. It is a function of identity.
A community where the median household earns $182,000 and votes for Bernie Sanders' co-chair is voting on identity, not economics. As immigration continues to transform districts across the country, the same dynamic will follow.
What It Means for 2028 and Beyond
Ro Khanna's 2028 presidential ambitions are not a long shot. They are a demographic inevitability.
As Asian Americans become a larger share of the electorate in Nevada, Virginia, Georgia, and North Carolina, candidates who speak to immigrant identity politics will have an increasingly viable path to national power.
Khanna is the prototype. An Indian American from a majority-Asian district. Fluent in progressive ideology. Backed by tech money. Positioned to mobilize the same demographic forces nationally that have made CA-17 a D+21 lock.
The question is not whether a Ro Khanna type will eventually win a presidential nomination. The question is whether the country will still be recognizable by the time it happens.
Silicon Valley in 1970 was an American community. Silicon Valley in 2025 is a global one. The people are different. The languages are different. The religions are different. The political outcomes are different.
The transformation was executed through immigration policy.
The Center for Assimilation advocates for the reforms that would prevent every American community from following Silicon Valley's trajectory:
- End the H-1B program as currently structured
- Reduce legal immigration by at least 50% to restore manageable numbers that allow assimilation
- Require English proficiency for permanent residency
- Geographic dispersal to prevent the concentrated settlement that creates ethnic enclaves and permanent voting blocs
- Skills-based selection only - end family chain migration that multiplies each admission into dozens
CA-17 is what happens when immigration runs unchecked for 35 years. It is the wealthiest district in America and politically unrecognizable. That is the future of every American community if nothing changes.
