When you look at a political map of Missouri, it usually looks like a sea of deep crimson. But then you spot those little islands of indigo. One of those—the brightest one, really—is St. Louis. If you’re asking is st louis a blue city, the short answer is a resounding yes. But the "how" and "why" behind that blue status are a lot more interesting than just a simple color on a map.
Honestly, it’s not even close. In the 2024 presidential election, St. Louis City went for Kamala Harris with about 81% of the vote. Compare that to the rest of the state, where Donald Trump cruised to victory with 58.5%. That's a massive gap. It basically shows that the city lives in a completely different political universe than the rural counties just an hour’s drive away.
Breaking Down the Blue: Is St. Louis a Blue City in Every Way?
You can’t talk about St. Louis politics without making a huge distinction: the City vs. the County. They are two separate entities, thanks to the "Great Divorce" of 1876.
St. Louis City is the urban core. It’s where the Gateway Arch is. It’s where you’ll find the deep, deep blue. The local government is dominated by Democrats. In fact, the city hasn't had a Republican mayor since the 1940s. While the current mayor, Cara Spencer, won a nonpartisan election in early 2025, she—like her predecessor Tishaura Jones—operates within a political ecosystem that is firmly liberal.
St. Louis County is the massive suburban ring around the city. It’s also blue, but a much lighter shade. In 2024, the County went for Harris by roughly 61%. That’s still a solid win, but it’s not the 80%+ blowout you see in the city limits. The County has more "purple" pockets, especially as you move west into places like Chesterfield or Wildwood, where you'll find more moderate or conservative voters.
Why the City Stays So Blue
It really comes down to demographics and density. Urban areas across the U.S. tend to lean left, and St. Louis is a textbook example.
- Diverse Population: The city has a high percentage of African American residents (about 43%), a group that historically votes overwhelmingly Democratic.
- Education Hubs: With institutions like Saint Louis University (SLU) and Washington University nearby, the city attracts a younger, highly educated demographic that leans progressive.
- Labor Unions: St. Louis has deep roots in organized labor. While some union members have shifted right in recent years, the institutional power of the unions in the city still largely backs Democratic candidates.
The Red State Reality
Even though St. Louis is a blue stronghold, it’s still strapped into the passenger seat of a red state. This creates a lot of friction. You’ve probably seen the headlines: the Missouri state legislature in Jefferson City frequently passes laws that tie the hands of St. Louis leaders.
Whether it’s gun control, minimum wage hikes, or police oversight, there’s a constant tug-of-war. For example, when St. Louis tried to raise its local minimum wage a few years back, the state stepped in and blocked it. This "preemption" is a huge part of the political identity here. Residents often feel like they’re living in a blue bubble that’s constantly being poked by a red needle.
Is St. Louis a Blue City? Looking at the 2024 and 2025 Results
If you look at the 2024 general election, the "blue" label is undeniable. Kamala Harris took 81.4% of the vote in the city. For the Senate race, Lucas Kunce (the Democrat) took about 80% in the city, even though he lost statewide to Josh Hawley.
Then you have the local 2025 mayoral race. Cara Spencer defeated incumbent Tishaura Jones. Now, some might look at an incumbent losing and think there's a shift. But both Spencer and Jones are Democrats. The debate wasn't about "Left vs. Right." It was about "Progressive vs. Moderate-Progressive" and, frankly, how to handle basic city services like trash pickup and crime.
In St. Louis, the real "general election" usually happens during the primary. By the time the final vote rolls around, the winner is almost guaranteed to be a Democrat.
Surprising Nuances
It isn't all 100% partisan. In 2024, Missouri voters passed Amendment 3, which protected abortion rights. While St. Louis City voted "Yes" by a massive margin (around 85%), the County also voted "Yes" by a lot. Interestingly, even some red counties across Missouri saw significant "Yes" votes. This suggests that while St. Louis is the leader of the blue pack, some of its liberal policies have more statewide support than the "Red State" label would suggest.
What This Means for You
If you’re moving to St. Louis or just trying to understand the vibe, here’s the deal:
If you’re a progressive: You’ll find your people in neighborhoods like Tower Grove South, the Central West End, or Cherokee Street. You’ll be surrounded by like-minded voters, and your local representatives will likely align with your values.
If you’re a conservative: You’re going to be a lonely voice in the city proper. Most conservatives in the region live in St. Charles County or the outer edges of St. Louis County, where the politics shift dramatically toward the GOP.
If you’re an observer: Understand that St. Louis is a city of contradictions. It’s a blue engine in a red machine. This tension defines almost everything—from how the police are funded to how the schools are run.
Actionable Takeaways for Understanding STL Politics
To get a real feel for the local landscape, don't just look at the "D" or "R" next to a name.
- Follow the Board of Aldermen: This is the city’s legislative body. This is where the real fights happen over development, tax breaks, and social programs.
- Watch the City-County Split: Keep an eye on any talk of a "merger." It’s a perennial topic that usually goes nowhere because of the political and economic differences between the two areas.
- Check Local Ballot Initiatives: Often, St. Louis voters use ballot measures to bypass the state legislature, though the state often tries to find ways to overturn them later.
St. Louis is, and will likely remain, one of the bluest spots in the Midwest. It’s a city that defines itself by its urban identity, its diversity, and its frequent clashes with the more conservative state government in Jefferson City.
