HELENA, Mont. (AP) — Montana Republicans gathered in a hotel ballroom this weekend aiming to unite ahead of the 2024 election and defeat three-term incumbent Democrat U.S. Sen. Jon Tester. Yet before the party even got underway it was crashed by conservative U.S. Rep. Matt Rosendale, who jumped into the race in defiance of GOP leaders.
Rosendale’s move laid bare deep fissures within the Montana GOP at a time when Republicans can ill afford it. Toppling Tester is a key part of their strategy to take control of the narrowly divided Senate in the November election by targeting vulnerable Democratic seats in Montana, Ohio and West Virginia.
Outside observers and even some Republicans say an intraparty skirmish leading up to Montana’s June primary could undermine those hopes.
Senate Republican leaders — including Sen. Steve Daines of Montana, who leads the National Republican Senatorial Committee — are backing a former U.S. Navy SEAL over Rosendale, who is viewed as too divisive to appeal to the state’s large contingent of independent voters.
Rosendale’s entry into the Senate contest capped months of speculation that the hard-right lawmaker wanted a rematch six years after losing to Tester in 2018.
“I’ve won two elections since then,” Rosendale, 63, told reporters after filing paperwork on Friday to formally enter the race. “And the most important thing is that my name I.D. and my trust factor is elevated dramatically. People know who I am.”
A large group of conservative state lawmakers showed up for Rosendale’s filing and boisterously cheered him on, underscoring his grassroots support in the state.
A few hours later and several blocks away, Montana Gov. Greg Gianforte took the stage in a Helena hotel ballroom to pump up former SEAL and political newcomer Tim Sheehy as the party’s best chance to beat Tester. Behind the Republican governor was a poster with the state GOP slogan, “We’re better, together!”
As Gianforte’s speech concluded a buzz ran through the crowd: Former President Donald Trump had just endorsed Sheehy in a social media post. “He probably heard my speech,” Gianforte quipped as an aide told him of the endorsement.
Rosendale, who Trump backed in 2018 and again in 2020, responded to the setback by reaffirming his fealty to the former president. “I love President Trump,” he said when asked about the endorsement.
Rosendale was among eight…
