Politics is messy. If you look at a standard red states and blue states map after an election, you see a country neatly sliced into two colors. It looks like a clean divorce. Huge swaths of crimson across the Great Plains and the South, punctuated by blocks of deep sapphire along the coasts and the Great Lakes. It’s visual shorthand. It’s also incredibly misleading.
Maps are tools, but they’re also filters. When we stare at that specific binary of red and blue, we’re seeing geography, not people. Land doesn't vote. People do. Yet, we’ve become obsessed with these colors as if they define our DNA.
The accidental history of the red states and blue states map
Believe it or not, these colors weren't always "settled science." Back in the day, TV networks just picked colors on a whim. During the 1976 election, NBC used red for Democrats and blue for Republicans. Why? Because red is the color of many liberal or labor parties globally. It made sense.
Then came the 2000 election. Bush vs. Gore.
The Florida recount dragged on for weeks. Day after day, news graphics stayed frozen on the screen. The New York Times and USA Today both used red for the GOP and blue for the Democrats in their printed maps. Because that election lasted forever in the public consciousness, the colors stuck. We just... stopped changing them. Before 2000, there was no such thing as a "blue state" identity. Now, it’s a lifestyle brand.
Beyond the sea of red
If you look at a red states and blue states map from the 2024 or 2020 cycles, the first thing that hits you is the sheer volume of red. It looks like Republicans win by a landslide every time.
But look closer.

The map shows acreage. It doesn't show density. A county in Nebraska might have 500 people and be 90% red. A single neighborhood in Brooklyn might have 50,000 people and be 90% blue. On a standard map, that Nebraska county takes up way more space, tricking your brain into thinking the country is "more red" than the popular vote actually suggests. This is what cartographers call the "land area bias." It's a huge reason why people get so confused when a candidate wins the popular vote but the map looks like a red ocean with a few blue islands.
Purple is the reality nobody wants to map
Honestly, every state is purple. Even the "deepest" red or blue states have massive minorities of the opposing party.
Take California. People call it the capital of the "blue states." But in the 2020 election, more than 6 million people in California voted for Donald Trump. That’s more Republican votes than any other state in the country, including Texas. Conversely, millions of Democrats live in rural Tennessee or Alabama. When we use a red states and blue states map that colors a whole state one shade based on a 51% win, we effectively erase millions of voters.
We’ve created a "winner-take-all" visual language that fuels polarization. If you live in a "blue state" but you're a conservative, you feel alienated. If you're a liberal in a "red state," you feel invisible.
The rise of the "Purple Map" or Cartogram
Experts like Mark Newman from the University of Michigan have tried to fix this. He creates cartograms—maps where the size of a state is distorted based on its population rather than its physical landmass.
When you look at a population-weighted red states and blue states map, the country looks totally different. The giant, empty red squares of the West shrink to tiny slivers. The coastal cities swell up like balloons. It’s ugly. It’s distorted. But it’s much more "true" to how the vote actually functions.

Some people prefer the "shaded" map. Instead of hard red or blue, it uses shades of purple. A state that goes 51% Republican is a light lavender-red. A state that goes 80% Republican is deep maroon. This shows the nuance. It shows that the "divide" isn't a brick wall; it's a gradient.
Why the "Blue Wall" and "Sun Belt" matter more than the whole map
In modern politics, we don't really watch 50 states. We watch about seven.
The "Blue Wall"—Pennsylvania, Michigan, and Wisconsin—usually determines if a Democrat wins. The "Sun Belt"—Arizona, Nevada, Georgia, and North Carolina—is where the GOP has to hold the line. Because of the Electoral College, the red states and blue states map is basically a high-stakes game of Tetris.
Candidates don't even visit 40 of the states. Why would they? If you're a Republican, you aren't spending money in California. If you're a Democrat, you aren't buying ads in Idaho. This creates a feedback loop. Voters in "safe" states feel ignored because, on the map, their destiny is already colored in years before the election even happens.
The urban-rural divide is the real story
If you want to understand the modern red states and blue states map, stop looking at state lines. Look at the city limits.
The biggest predictor of how a precinct will vote isn't which state it’s in—it's how close the houses are to each other. Densely populated areas vote blue. Sparsely populated areas vote red. This is true in "blue" New York and "red" Texas. Austin, Texas, looks more like Seattle than it looks like the Texas Panhandle.

This is the "Big Sort." People are moving to places where they feel culturally aligned with their neighbors. This makes the colors on our maps even more vibrant and the "middle ground" even harder to find.
How to read the map like a pro in the next election
Next time you see a red states and blue states map on a news site, don't just look at the colors.
- Check the "Margin of Victory": A state that's red by 0.5% is fundamentally different from a state that's red by 20%. Don't let the solid color fool you into thinking the state is a monolith.
- Look for the "Bubbles": Most interactive maps now let you see "circles" representing vote counts. Big circles mean lots of people. Small circles mean lots of land. Focus on the big circles.
- Ignore the early results: Because of how mail-in ballots are counted (which often lean blue) versus in-person day-of voting (which often leans red), the map will "shift" colors throughout the night. This is often called the "Red Mirage" or "Blue Shift."
The map is a snapshot. It’s not a permanent destiny. If you look at a red states and blue states map from 1984, almost the entire country was red for Ronald Reagan. In 1964, it was almost entirely blue for Lyndon B. Johnson.
Colors change. Populations move. The map you see today is just a temporary arrangement of a very fluid country.
To get a real sense of the political landscape, stop looking at the 50 states. Start looking at the counties, the suburbs, and the shifting demographics. The map is just paper; the people are the ones who actually make it move.
Actionable Insights for the Curious Voter:
- Use Interactive Cartograms: Visit sites like the University of Michigan’s Physics department or Worldmapper to see "population-accurate" versions of the election results.
- Follow County-Level Data: Use resources like the Dave’s Redistricting App to see how your specific neighborhood fits into the larger color scheme.
- Track Demographic Shifts: Watch the "swing" counties (like Erie, PA or Maricopa, AZ) rather than the "safe" states to understand where the country is actually heading.
- Diversify Your News Intake: If you only look at maps from one partisan source, you'll miss the context of "why" a state turned a certain color.
