Former President Donald Trump is set to hold a rally in Bozeman, Montana, aiming to bolster Republican efforts to unseat Democratic Senator Jon Tester, a crucial race for Senate control. This rally marks Trump's first since Vice President Kamala Harris secured her nomination and selected Minnesota Gov. Tim Walz as her running mate, both moves that have energized the Democratic base. Tester is attempting to align himself with Trump on various issues, while his opponent, Republican Tim Sheehy, hopes to leverage Trump's popularity to gain support. The rally is expected to draw significant GOP turnout and could influence the election by having Trump's name on the ballot alongside Sheehy. Trump, who previously campaigned in Montana in 2018 but failed to unseat Tester, faces pressure as he navigates a more competitive electoral landscape this fall. The event underscores the strategic importance of Montana in the upcoming elections, with fundraising stops planned in Wyoming and Colorado as well.
