The Club for Growth announced Tuesday it will not support Rep. Steve Stockman’s primary bid to unseat Sen. John Cornyn, R-Texas.

“While Congressman Stockman has a pro-economic growth record, so does Senator Cornyn, as witnessed by his 87% lifetime Club for Growth score,” Club for Growth President Chris Chocola said in a statement.

“Our PAC evaluates three factors when looking at races that involve incumbents: 1) the strength of the incumbent’s record; 2) the degree of difference between the incumbent and the challenger on economic issues; and 3) the viability of the challenger. None of those factors weigh against Senator Cornyn, so we do not expect to be involved in the Texas Senate race.”
