At a Tucson Tea Party rally Wednesday, Pennsylvanian urges the crowd to vote for “who’s authentic.”

Santorum: “Look at the record versus the rhetoric of what you see of, in many cases, Johnny-Come-Latelys to the conservative cause. That’s the decision you have to make here in Arizona. Who do you trust? Who’s authentic? Who’s believable? Is it the guy reading from the teleprompter or the guy out here on a high-wire line telling you what’s in his heart and what’s in his gut.”
