Georgia Republicans selected U.S. Representative Mike Collins as their nominee for the U.S. Senate, choosing President Donald Trump's preferred candidate in a runoff election over political outsider Derek Dooley. Collins, who secured Trump's endorsement over the weekend, will face incumbent Democratic Senator Jon Ossoff in November. Ossoff, who is the only incumbent Senate Democrat up for reelection in a state Trump won in 2024, is considered a strong contender due to his substantial fundraising and constituent services operation. Political prognosticators suggest Ossoff is favored to win reelection, despite Collins's status as a staunch Trump ally. The Democratic Senate Majority PAC has reserved $20 million in TV advertising in Georgia, while the Republican Senate Leadership Fund has pledged $44 million to support flipping the seat.
