Incumbent Democratic Sen. Jon Tester is trailing behind Republican challenger Tim Sheehy in the Montana Senate race, according to a recent AARP poll. Sheehy, a former Navy SEAL, leads Tester by six points in a direct matchup (51% to 45%) and by eight points when third-party candidates are included. This race is crucial as it could determine which party controls the Senate, especially with West Virginia expected to flip Republican. Voters over 50, who make up a significant portion of the electorate, are primarily concerned with issues like Social Security, Medicare, and rising prices. The Democratic Party has heavily invested in the race, with $128 million in advertising, but the GOP remains optimistic about Sheehy's chances, bolstered by former President Trump's strong support in the state.
