Lt. Gov. David Dewhurst brought out former Arkansas Gov. Mike Huckabee for a second television ad Thursday to highlight Dewhurst's anti-abortion credentials.

"David’s conservative leadership helped Texas pass more pro-life legislation than any state in America," Huckabee says in the ad. "And David stood with taxpayers, cut spending and cut taxes. There’s only one proven conservative in this race for Senate, so stand with him."

The ad will air "in select markets across Texas," campaign spokesman Matt Hirsch said. He declined to say whether the ad will air on broadcast or cable networks or both.

Dewhurst previously featured Huckabee in a television ad in January.
