Aug. 2, 2017 — Republicans have been working to recruit a top-tier challenger to two-term Sen. Jon Tester (D), and yesterday they identified such an individual. Montana Commissioner of Insurance and State Auditor Matt Rosendale announced that he will join the Republican primary, vying to become the party nominee and oppose Sen. Tester in the next election.
Rosendale was first elected to his statewide position just last November, so he is quickly making the move for federal office. Prior to running for auditor, he served a term in the state House of Representatives and a pair of consecutive two-year stints in the state Senate, representing the Glendive area in Montana’s far eastern sector. In the 2015-16 session, Rosendale was the Senate Majority Leader.
In 2016, he ran to succeed Democratic Auditor Monica Lindeen who was ineligible to seek a third term. Rosendale defeated former state Rep. Jesse Laslovich (D), 54-46 percent, from an electorate of more than 486,000 voters.
