The upcoming May 19 Republican primary for Georgia's U.S. Senate seat features a fragmented field where no candidate has secured a majority in recent surveys, positioning the contest for a potential June 16 runoff. Mike Collins maintains a polling edge through his House tenure, consistent fundraising leadership, and established campaign infrastructure, which traders interpret as advantages in a race against Democratic incumbent Jon Ossoff. Derek Dooley has narrowed the gap via rising name recognition from his coaching background, television advertising, and support from Governor Brian Kemp, drawing undecided voters in the final weeks. Earl Carter trails further behind despite early ad spending. With over half of likely primary participants still uncommitted, the outcome remains sensitive to turnout and last-minute shifts.
