WASHINGTON—Conservative activists, energized by their defeat of Sen. Richard Lugar, are turning their fire to other established Republicans facing primaries, a bid to prove to opponents their Indiana victory wasn’t a fluke.
The first test comes next Tuesday, when Nebraska attorney general Jon Bruning faces a tea-party-backed challenge from state treasurer Don Stenberg in a Senate Republican primary.
A Texas contest comes two weeks later. The Club for Growth, a small-government group that helped oust Mr. Lugar, said Wednesday it will spend $1 million to support former Texas solicitor general Ted Cruz, who’s trying to wrest a Senate nomination from establishment favorite Lt. Gov. David Dewhurst.
