The same group that helped defeat longtime U.S. Senator Richard Lugar in the Indiana Republican Primary, is now backing Ted Cruz in an effort to defeat frontrunner David Dewhurst, in the form of lots of cash. The Washington-based Tea Party Club for Growth rolled out a one millon dollar ad campaign against "moderate tax-raising David Dewhurst."

"Texans looking for a principled defender of economic freedom should vote for Ted Cruz in the Republican Primary for U.S. Senate,” said Club for Growth President Chris Chocola in a press release. “Texas newspapers describe David Dewhurst as a moderate at heart because he has grown the size of government, supported new taxes, and has done his best to stop conservative policies in Austin. Texas Republicans should vote against David Dewhurst and his support for higher taxes on May 29th.”

The Dewhurst campaign released a new ad today as well, starring Mike Huckabee.

"We need different people in Washington with different values – conservative people like David Dewhurst," Huckabee says in the ad. "David’s conservative leadership helped Texas pass more pro-life legislation than any state in America. 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."
