A Montana farmer with a flattop and ample lobbyist cash stands between the GOP and Senate control

BIGFORK, Mont. (AP) — After 17 years in the U.S. Senate, Democrat Jon Tester is a well-known commodity in Montana — a plain-spoken grain farmer with a flattop and a carefully cultivated reputation as a moderate.

The 67-year-old lawmaker smiled and laughed his way through the crowd at a Veterans Day event in Bigfork, a small town on Flathead Lake where the population has surged in recent years. He chatted with veterans who supported him and some who didn’t, then stood behind a lectern in the Bigfork High School gymnasium to promote his biggest recent accomplishment: expanded federal health care for millions of veterans exposed to toxic smoke at military “burn pits."

Tester has survived three close elections and a changed national political landscape to emerge as the lone Democrat still holding high office in Montana. The 2024 election brings possibly his stiffest challenge yet: Republicans, just two seats short of Senate control, are expected to spend tens of millions on attack ads painting him as a Washington insider tainted by lobbyist cash.

Ousting Tester also would cement a Republican lock on a state that voted overwhelmingly for Republican Donald Trump in the 2020 presidential election.

Tester entered the Senate after selling Montana voters on his authenticity, and the former high school band teacher's message hasn’t changed much. He still mingles comfortably with union members, ranchers and veterans, has a record of working on their behalf, and says his heart remains firmly in his sparsely populated state, a vast expanse that spans from the arid Great Plains to the lush forests of the Pacific Northwest.

Still, authenticity is harder to sell when you’ve become a top Washington fundraiser. He's taken in almost $20 million for next year's election, ranking Tester sixth among Senate candidates nationwide, according to Federal Election Commission data through September. Tester insisted that the money hasn’t changed him, that he doesn’t even know where it all comes from.

“I can’t tell you who’s donating to me. Even from within the state of Montana, I can’t tell you who donates to me because I don’t look at that list,” he said in an interview. “It’s not important. I trust that those people believe in me and I’m going to continue to do the same job.”

His campaign reports reveal abundant lobbyist cash, the kind that rarely comes from people who don't want something, and yet the lawmaker's journey from outsider to fundraising behemoth has largely been one of necessity. With West Virginia Democratic Sen. Joe Manchin's decision against seeking another term, Tester has become a top target for Senate Minority Leader Mitch McConnell, R-Ky., and his massive fundraising operation.
