ALPHARETTA, Ga. (AP) -- Republicans are trying to prevent a major upset stoked by opposition to President Donald Trump in a conservative congressional district in Georgia.
Tuesday's jungle-style primary lumps all 18 candidates on one ballot. The leading Democrat, 30-year-old Jon Ossoff, needs to clear 50 percent to avoid a June runoff.
Polls put Ossoff in the lead but short of that margin. Four of the 11 Republican candidates are fighting for the No. 2 spot, limiting their ability to focus on Ossoff.
Both national parties have paid field staffers working the race for the seat Tom Price resigned to become Trump's health secretary. Ossoff supporters have contributed more than $8 million.
A political action committee backed by House Speaker Paul Ryan has spent more than $2 million attacking Ossoff.
