MADISON, Wis. (AP) — Wisconsin’s hotly contested U.S. Senate race pits two-term Democratic incumbent Tammy Baldwin against Republican Eric Hovde, a millionaire businessman backed by former President Donald Trump who poured millions of his own money into the contest.

A win by Baldwin is crucial for Democrats to retain their 51-49 majority in the Senate. Democrats are defending 23 seats, including three held by independents who caucus with them. That’s compared with just 11 seats that Republicans hope to keep in their column.

While Baldwin’s voting record is liberal, she emphasized bipartisanship throughout the campaign. Baldwin became the first statewide Democratic candidate to win an endorsement from the Wisconsin Farm Bureau, the state’s largest farm organization, in more than 20 years.

Her first television ad noted that her buy-American bill was signed into law by Trump. In July, she touted Senate committee approval of a bill she co-authored with Trump’s running mate, Sen. JD Vance, that seeks to ensure that taxpayer-funded inventions are manufactured in the United States.

Hovde tried to portray Baldwin as an out-of-touch liberal career politician who didn’t do enough to combat inflation, illegal immigration and crime.

Hovde’s wealth, primarily his management of Utah-based Sunwest Bank and ownership of a $7 million Laguna Beach, California, estate, has been a key line of attack from Baldwin, who has tried to cast him as an outsider who doesn’t represent Wisconsin values.

Baldwin also attacked Hovde over his opposition to abortion rights.

Hovde said he supported the Supreme Court’s overturning of Roe v. Wade in 2022, but said he would not vote for a federal law banning abortion, leaving it to the states to decide. That is a change of his position from his last run for Senate in 2012, when he “totally opposed” abortion.

Baldwin’s television ads hit on a consistent theme that Hovde insulted farmers, older residents, parents and others. Hovde, who was born in Madison and owns a house there, accused Baldwin of distorting his comments, lying about his record and misleading voters.

Baldwin won her first Senate race in 2012, against popular former Republican Gov. Tommy Thompson, by almost 6 percentage points. Hovde lost to Thompson in that year’s primary.

Hovde attacked Baldwin for being in elected office since 1987, including the past 12 years in the Senate and 14 in the House before that.
