A new statewide ad from "Big Bold Texan" Ron Paul hit airwaves Tuesday, the same day he kicks off a three-day, three-city tour of town hall meetings here in Texas. In the 30-second ad Paul calls Rick Santorum a "big spending, debt ceiling raising fiscal liberal," and says Mitt Romney is a "moderate from Massachusetts." You see a brief picture of Newt Gingrich, who is only referred to as the "Moon Colony Guy."

"Only one candidate can stand up for Texas," the ad says, referring to Paul.

In a press release about the "Vote Texas" ad, Paul campaign Chairman Jesse Benton says, "Ron Paul is competing hard in his home state of Texas, and we expect that Texas conservatives will reject flip-flopping Massachusetts moderate Mitt Romney and the debt ceiling raising fiscal liberal Rick Santorum.

"Through ‘Vote Texas’ and the campaign’s other efforts, Texas voters will be reminded that Ron Paul is the only Texan in the race, the only veteran in the race, and the only real conservative in the race."
