This story is part of a series of state-by-state previews of the 2024 election.
Wisconsin is no stranger to close presidential elections. The margin of victory was less than a percentage point in the state's 2020, 2016, 2004, and 2000 elections. So it might be again this Election Day.
Both Republican Donald Trump and Democratic Vice President Kamala Harris are competing hard for the 10 electoral votes at stake in Wisconsin, making frequent stops in the Badger State—including several in the vote-rich Milwaukee, Madison, and Green Bay areas.
Wisconsin was one of three “blue wall” states (Michigan and Pennsylvania are the others) that went narrowly for Trump in 2016 after almost 30 years of voting for Democratic presidential candidates. Four years later, Democrat Joe Biden won all three states back for Democrats with a margin in Wisconsin of about 20,000 votes out of nearly 3.3 million votes cast.
