America's Biggest Cities Have Been Blue for a Century

Why Cities Stay Blue and What Republicans Are Doing About It

Republicans have spent decades insisting that Democratic governance destroys cities. But no one can prove their point.

As of March 2026, 67 of the 100 largest cities in the United States have Democratic mayors. That number has held steady since at least 2016, fluctuating by only a handful of seats in either direction regardless of national political conditions. New York, Los Angeles, Chicago, Houston, Philadelphia, San Antonio, and San Diego all have Democratic mayors simultaneously. These are the economic engines of the country, and they have been governed by one party for the better part of a century.

Chicago has not elected a Republican mayor since 1931, when Anton Cermak took office and started a Democratic streak that has now outlasted every living American political career. The city runs the third-largest metropolitan economy in the United States and processes more railroad freight than any other city in the country. Whatever Chicago is supposedly doing wrong, it has managed to do it profitably for nearly a century.

Atlanta mirrors the same dynamic, with considerably more irony. It anchors Georgia's economy from inside a reliably Republican state. Thirty-three companies with headquarters in metro Atlanta rank among the 2024 Fortune 1000. Georgia has a Republican governor and a Republican-controlled legislature. The state collects Atlanta's tax revenue and leaves the politics alone.

How is this possible?

Density creates interdependence. When millions of people share transit systems, water infrastructure, school districts, and emergency services, collective governance becomes a logistical necessity rather than an ideological preference. Urban residents vote Democratic because the problems they face — housing costs, wage floors, public health infrastructure — require coordination at scale. Republican governance, built around deregulation and individual autonomy, functions more effectively in lower-density environments where those problems rarely intersect.

Philadelphia is a city that has voted Democratic in every presidential election since 1940. It delivered Pennsylvania's electoral votes for Joe Biden in 2020 and remained competitive for Democrats in 2024. The surrounding counties vote Republican. Philadelphia produces margins large enough to neutralize them, and Pennsylvania keeps funding rural counties that exist in structural opposition to the city producing the revenue.

The conservative critique of urban Democratic governance rests on crime statistics, population outflows, and homelessness data, and those numbers contain legitimate concerns. Chicago's violence on the South and West sides is documented and serious. San Francisco's dysfunction is measurable. What the critique does not account for is that the largest, wealthiest, most economically significant cities in America have been blue for generations and continue to drive national output. The argument that Democratic cities are failing sits uncomfortably alongside the fact that the country's economy is built on top of them.

When cities can't be won, the map becomes the weapon. Lose the city, redraw the map. Republicans control enough state legislatures to draw congressional districts that concentrate Democratic voters into as few seats as possible while spreading Republican voters across a larger number of winnable ones. The Supreme Court's 2019 decision in Rucho v. Common Cause removed federal courts as a check on this practice, ruling 5-4 that partisan gerrymandering presents a political question beyond federal judicial reach. State-level map-drawing became considerably more aggressive in the years following that decision.

The Trump administration has pursued structural advantages beyond redistricting. In March 2025, Trump signed an executive order attempting to require documentary proof of citizenship on federal voter registration forms. A federal court permanently blocked that provision by October 2025, finding the president lacks unilateral authority over election procedures that belong to Congress and the states. The Department of Justice sent demand letters to at least 38 states requesting access to voter rolls and list maintenance records. When eight states refused, including California, Michigan, New York, and Pennsylvania, DOJ sued them. The administration also ran voter data on more than 33 million Americans through a DHS database system that experts warned contained inadequate safeguards, producing errors that disproportionately flagged naturalized citizens and Americans born before 1978.

The birthright citizenship executive order, signed on Trump's first day back in office, targets the same population through a different mechanism. Every federal court that reviewed it struck it down. After oral arguments in April 2026, a majority of Supreme Court justices appeared likely to rule against the administration. The order remains blocked. Urban populations are denser, more diverse, and more likely to include the residents these policies would reclassify or remove from voter rolls. The geographic logic is consistent across all of it.

The cities are not trending red.

The suburbs are the battleground now, the exurbs are the base, and the cities remain what they have always been. The money is made there, the votes are cast there, and the maps are being redrawn by the people who lost both.
