Republicans are increasingly concerned about Georgia’s Senate race, where a crowded primary threatens to produce a flawed candidate who could put at risk a seat in a Republican-leaning state.

Recent polling shows the two candidates Republicans are most anxious about — Reps. Phil Gingrey (R-Ga.) and Paul Broun (R-Ga.) — leading the pack. Whoever emerges from the clown-car primary, with seven candidates and counting, will face a candidate Democrats are high on in a state where shifting demographics benefit their party.

Losing Georgia’s open Senate seat would do severe damage to Republicans’ hopes of winning the net of six seats necessary to take control of the Senate.

“Gingrey has a history of making some gaffes, and Broun it seems like it’s a gaffe every other day. Those are the two that worry Republicans the most as potential problems going into the general election,” said Georgia Republican strategist Joel McElhannon, who’s neutral in the race.
