Now that U.S. Rep. Mike Collins has announced his run for Jon Ossoff's Georgia seat in the Senate, here is everyone else who has launched a campaign.

Collins had been considering a Senate run since Georgia Governor Brian Kemp announced in May that he would not run against Ossoff, AP reported. Ossoff and Raphael Warnock delivered a massive win to Democrats when they picked up Georgia's two Senate seats in 2020, the first time in 15 years that Georgia was represented by two Democratic senators.

Rep. Mike Collins (R-Ga.) on Monday announced his bid for the Senate in next year’s midterms, joining a now-contested GOP primary of hopefuls attempting to unseat Democratic Sen. Jon Ossoff.
