Tomorrow's elections

Key things to know about tomorrow's elections — and why they are seen as a test of Trump's second term

Tuesday marks the first major election night of Donald Trump’s second term. The highest profile race will be in the critical swing state of Wisconsin, where voters will determine ideological control of the state Supreme Court.

Meanwhile, there will be two special congressional elections in solidly Republican Florida districts where both sides will be watching the margins for clues about party enthusiasm.

More on the races: The Wisconsin Supreme Court race features Republican-backed judge Brad Schimel and Democratic-backed judge Susan Crawford to determine if the highest court in the Badger State will retain its 4-3 liberal majority.

In Florida, there are special elections in the 1st and 6th congressional districts to fill seats vacated by former Republican Reps. Matt Gaetz and Michael Waltz.

Trump-endorsed Republican candidates Jimmy Patronis, the state’s outgoing chief financial officer, in the 1st district and outgoing state Sen. Randy Fine in the 6th district are both favored to hold the seats for their party and give the narrow GOP majority in the House a bit more breathing room, although some Republicans have expressed concern about Fine’s candidacy and fundraising in the closing days of the race.

Also on the ballot in Wisconsin, Democratic-backed state Superintendent of Public Instruction Jill Underly faces a conservative-backed challenge from education consultant Brittany Kinser. There’s also a measure to add a voter ID requirement to the state constitution. Photo identification is already required to vote in Wisconsin by state law.
