First it was Jim DeMint, then Ron Paul and Sarah Palin. Now, Ted Cruz is getting the strong backing of another Tea Party rock star: Rick Santorum. Santorum appeared on Glenn Beck’s radio show Thursday morning.

"This is a tough race because there’s some very good people in this race but to me Ted is, what we’re missing in the United States Senate," Santorum said. "There’s no one out there that can get up there and deliver the kind of impassioned, spellbinding speeches and really engage the debate on the floor of the United States Senate…Ted Cruz, I’ve seen him speak, and he is spellbinding. He really is. He’s just a tremendous orator and very strongly principled, in-depth. I mean, he understands these issues at his core and can really deliver the message. And we do need, not just people who are good votes, but people who can really motivate and lead."

Santorum said he waited to endorse anyone in the GOP Senate primary, but said he related to how Cruz has been out spent by Dewhurst, and he gravitates to the underdog.

"There’s a kindred spirit when you’re the underdog and you’re being out spent and someone whose got the grassroots support and is working their tail off every day and you know, that’s the kind of candidate that I was and I sort of gravitate to, so I’m excited to be involved in his campaign and I will be doing all I can between now and Tuesday to help him out and make sure he’s at least in [the] runoff and who knows, maybe he can surge ahead and pull a big surprise."
