Rep. Renee Ellmers (R-N.C.) will run for reelection next year, passing up an opportunity to challenge Sen. Kay Hagan (D).
Her decision is bad news for Republicans who hope the party can win Hagan's seat and take back the Senate. House Speaker Thom Tillis is already in the race, but he hasn't raised much money and has faced some negative press. Senate President Phil Berger is considering a bid.
Had she run, Ellmers would have had to deal with blowback from the anti-tax Club for Growth, which has targeted her as too moderate.
