"Montana Senate Race Heats Up: Rosendale Launches Bid Amid Divisive GOP Primary"

Rep. Matt Rosendale launches his campaign for the Montana Senate, setting the stage for a contentious GOP primary against former Navy SEAL Tim Sheehy, who has received endorsements from the National Republican Senatorial Committee and former President Donald Trump. The primary is scheduled for June 4, and the winner will face Democratic incumbent Sen. Jon Tester in a state crucial for the balance of power in the Senate. Rosendale's entry has sparked intraparty hostility, with NRSC Chairman Steve Daines criticizing his decision, while Trump's aides express frustration over what they view as Rosendale’s lack of loyalty. Tester, a formidable opponent, has been actively building his campaign coffers and dominating the airwaves with ads. The race is also influenced by external dynamics, including endorsements and support from Trump allies.
