Get Glenn Live! On TheBlaze TV

At the start of the radio show this morning, Rick Santorum made a major endorsement of Texas Senatorial candidate Ted Cruz. Later in the show, Cruz called in to give his reaction and to discuss why this election season is important, not just for the Presidency but for all of Congress.

“You know, the fight for liberty, which is unifying conservatives across the spectrum, is the fight to save our country. And if we don’t get back to the Constitution, we’re going to lose liberty,” Cruz said.

Cruz noted he had received endorsements from Sarah Palin, Rand Paul, and Ron Paul in addition to the one from Santorum today.

“I’ll tell you it is an incredible blessing to be the child of an immigrant who fled oppression because it makes you realize how fragile liberty is and how precious it is. We are a shining city on a hill, as Reagan famously put it. And when you remember those stakes, then, you know, a bunch of fat cats in Washington that are just trying to spend our money don’t seem all that scary. You know, I’d much rather stand with the citizens and patriots across Texas and across the country reclaiming liberty and reclaiming the Constitution than with a whole bunch of lobbyists that just want to suckle on the teat of government,” Cruz explained.

Ted Cruz faces Lt. Gov. David Dewhurst and former Dallas Mayor Tom Leppert in a primary next Tuesday.
