It was almost 2:30 in the morning when the call finally came. For hours, the entire country had been staring at a map of the Dairy State, watching those red and blue pixels flicker as the "Blue Wall" either held firm or crumbled. Donald Trump won Wisconsin in 2024. Honestly, it wasn't a huge surprise to anyone watching the late-night returns from the Fox Valley or the drift in the rural north, but the margin was paper-thin.
He didn't just win; he reclaimed a state that had slipped through his fingers four years prior. The final tally, certified later by Wisconsin Elections Commission Chair Ann Jacobs, showed Trump with 1,697,626 votes compared to Kamala Harris's 1,668,229. That’s a gap of roughly 29,397 votes. In a state where 3.4 million people showed up—the highest turnout in the state's history—that tiny sliver made all the difference.
The Numbers Behind the Win
Wisconsin is famous for these "razor" margins. It basically always comes down to about 20,000 or 30,000 votes. In 2016, Trump won by about 22,000. In 2020, Biden took it by 20,000. This time, the 0.86% margin of victory made Wisconsin the closest state in the entire 2024 election. It was the only state in the whole country decided by less than one percentage point.
If you look at the map, you see a sea of red with a few islands of deep blue. But the real story is in how those colors shifted. Trump actually improved his performance in 71 out of 72 counties compared to 2020. Even in deep-blue Dane County—home to Madison and a massive university population—Trump managed to grab about one in every four votes. That’s a small gain, sure, but when you're fighting for every single ballot, it's huge.
Why the "WOW" Counties Mattered
For years, political nerds have obsessed over the "WOW" counties: Waukesha, Ozaukee, and Washington. These are the suburban strongholds around Milwaukee. Historically, they are the engine of the Wisconsin GOP.
Something weird happened here, though. While Trump won them, his margins weren't as "Republican" as they used to be in the pre-Trump era. For instance, in Waukesha, he pulled about 59.2%. That sounds high, but for a Republican in Waukesha? It's actually a bit low. Harris actually improved her standing in these suburbs, but it simply wasn't enough to offset the massive wave of support Trump was getting in rural areas and small towns.
What Flipped the State?
You've got to look at the "low-propensity" voters. These are people who don't always vote, or maybe they haven't voted in a decade. In 2024, they showed up for Trump. According to analysis from the Marquette University Law School, these infrequent voters disproportionately backed the Republican ticket.
The issues were pretty straightforward. AP VoteCast surveys showed that Wisconsin voters trusted Trump more on the economy and immigration. When you're paying $4 for a gallon of milk in Eau Claire, "saving democracy" as a campaign slogan feels a little abstract. Trump’s focus on inflation and the border resonated in the Northwoods and the manufacturing towns along Lake Michigan.
The Urban Drift
Milwaukee is always the "big reveal" of Wisconsin elections. This year, the city's results were released in a massive late-night batch. While Harris won Milwaukee County handily with about 68.3% of the vote, her support among Black and Latino voters dipped slightly compared to Joe Biden's 2020 numbers.
Roughly 8 in 10 Black voters backed Harris, which sounds dominant, but Biden had about 9 in 10. That small 10% shift is a earthquake in a state decided by less than 1%. It’s basically the reason the "Blue Wall" had a hole in it this time around.
The Certification was Quiet
Unlike the 2020 cycle, which was filled with lawsuits, recounts, and heated protests at the Madison capitol, the 2024 certification was surprisingly chill. It happened over a six-minute Zoom call. No drama. No shouting. Just Ann Jacobs signing the papers that confirmed Trump had secured the state’s 10 electoral votes.
It’s worth noting that even though Trump won the top of the ticket, Democrats had some silver linings. Tammy Baldwin managed to hold onto her U.S. Senate seat, defeating Eric Hovde in another nail-biter. This "split-ticket" voting shows that a decent chunk of Wisconsinites aren't strictly partisan; they might like a Republican for President but prefer a Democrat for the Senate.
Takeaways for the Future
If you’re trying to understand Wisconsin politics, the main thing to remember is that it’s a game of inches. The state is almost perfectly divided.
- Watch the margins in Madison and Milwaukee. If Democrats don't hit massive "run-up-the-score" numbers there, they lose the state.
- Rural Wisconsin is getting redder. Counties like Grant and Dodge are moving further away from the Democratic party every cycle.
- Turnout is king. With 72.6% of the voting-age population showing up, Wisconsin proves that its citizens are deeply engaged—even if they’re deeply divided.
To stay informed on how these results might affect local policy or the next round of midterms, it’s a good idea to follow non-partisan trackers like the Wisconsin Elections Commission or the Marquette Law School Poll. They provide the raw data without the spin.

The 2024 results basically cemented Wisconsin’s status as the ultimate "tipping point" state. It’s been the state that put the winner over the top in several recent elections, and looking at the numbers, it’s probably going to stay that way for a long time.
