Texas senatorial candidate, David Dewhurst, released a new spot this afternoon, featuring surrogate Mike Huckabee making the claim that Dewhurst is the true conservative.
As the Dallas Morning News notes, the new ad comes just hours after Sarah Palin announced she's backing Dewhurst's rival for the GOP nomination, Ted Cruz.
The Hill's Cameron Joseph has a good report on the race today, where the insurgent, Tea Party favorite Cruz is apparently closing the gap with Dewhurst.
Dewhurst has millions to spend on the race and can give his campaign even more thanks to his considerable wealth. Former Dallas Mayor Tom Leppert (R) is also spending millions of dollars of his own money on the race.
But polls show the contest tightening some — and a number of conservative organizations are ready to jump in for Cruz in a big way. The fiscally conservative Club for Growth promised earlier this week to spend $1 million on his behalf heading into the late May primary. If no one wins 50 percent of the vote, a runoff will be held in late June.
