Georgia Republican Sen. David Perdue is fighting to win his second term, facing Democratic filmmaker Jon Ossoff in November.

The contest offers a chance of political redemption for Ossoff, who mounted a failed bid for Congress in 2017 during a special election in Georgia’s 6th District. Early in President Trump’s tenure, Ossoff became a resistance hero of sorts, attracting national attention and money. The race for the suburban Atlanta seat turned into one of the most expensive House races ever, with both Ossoff and Republican Karen Handel raising over $55 million combined.
