Johnson announced his decision via email two days after a pair of Republicans with knowledge of his decision told The Associated Press that he was close to launching a bid. Johnson over the past year has been a leading voice in downplaying the Jan. 6, 2021, Capitol riot and the coronavirus pandemic, in addition to remaining a vocal Trump supporter.
The race is sure to be one of the most hotly contested in the country next year in purple Wisconsin. President Joe Biden won the state by fewer than 21,000 votes in 2020 after a similarly narrow win by Trump in 2016. Johnson won by nearly 5 points in 2010, his first race for office, and then by just over 3 points in 2016. Both times he defeated Democrat Russ Feingold.
Johnson's announcement that he will run again came a day after Republican Sen. John Thune, of South Dakota, said he would seek a fourth term. No other Senate retirements are likely beyond the five Republicans and one Democrat, Sen. Patrick Leahy of Vermont, who have already announced plans to step down.
Johnson, 66, had long said his preference was to serve just two terms and pledged in 2016 not to run a third time.
But Johnson rescinded the pledge in the lead-up to announcing his reelection bid, saying circumstances have changed after Democrats won the White House and control of Congress.
“Much as I’d like to ease into a quiet retirement, I don’t feel I should,” Johnson wrote in an editorial announcing his reelection bid. He said the response to the coronavirus pandemic also played a part in his decision to run again.
Johnson, who contracted COVID-19 in October 2020 and is not vaccinated, has cast doubt over the efficacy of vaccines and pushed for other forms of treatment. Just last week, Johnson on conservative talk radio said, “Why do we think that we can create something better than God in terms of combating disease? Why do we assume that the body’s natural immune system isn’t the marvel that it really is?”
Johnson has downplayed the violence at last year's Capitol raid, saying it “didn’t seem like an armed insurrection to me.”
Just before the U.S. Capitol was stormed a year ago, Johnson objected to counting the Electoral College votes from Arizona. Last year, he told Republicans who control the Wisconsin Legislature that they should take over control of federal elections. Republican Wisconsin Assembly Speaker Robin Vos told the AP on Friday that there is “zero chance” of the Legislature taking over the awarding of the state’s 10 presidential elector votes in 2024.
Johnson said he did not make the decision to run again lightly.
“Having already experienced a growing level of vitriol and false attacks, I certainly don’t expect better treatment in the future,” he said in his announcement.
Johnson said he never voted with reelection in mind.
“An extension of that promise is that I don’t conduct myself worrying about re-election," he wrote. "When re-election is not your primary motivation, those are easy promises to keep -- and I have faithfully done so.”
Johnson’s opponent won’t be known this time until after an Aug. 9 primary. Several high-profile and well-funded Democrats are running, including Lt. Gov. Mandela Barnes, who is seeking to become the state’s first black senator; Milwaukee Bucks executive Alex Lasry; state Treasurer Sarah Godlewski and Outagamie County Executive Tom Nelson.
Johnson’s decision also has ripple effects on Wisconsin’s governor’s race. Kevin Nicholson, a former Marine who ran for U.S. Senate and lost in the GOP primary in 2018, has said he would run for governor if Johnson sought reelection.
History is on Johnson’s side in the midterm election. The party that does not hold the White House generally gains seats in midterm congressional elections. Former President Barack Obama’s Democratic Party, for example, lost 63 seats in the House and six in the Senate in 2010.
Johnson, who rose out of the tea party movement in 2010, has long been aligned with Trump’s hardline policies and politics. The two have remained close following Trump’s defeat, with Trump in April endorsing Johnson for a third term and encouraging him to run.
