Cain got 27 percent to Perry’s 26 percent among Texas registered voters who identify themselves as Republicans. U.S. Rep. Ron Paul was next with 12 percent, followed by former Massachusetts Gov. Mitt Romney at 9 percent and former U.S. House Speaker Newt Gingrich at 8 percent. The other Republican primary candidates — Michele Bachmann, Jon Huntsman, Gary Johnson and Rick Santorum — each got 2 percent or less; 11 percent of the respondents answered “don’t know,” and another 1 percent said they would prefer “another Republican candidate.”

“Texans appear to be subject to the national dynamic,” said Jim Henson, who teaches government at UT, runs the Texas Politics Project there and co-directs the UT/Tribune poll. “And the dynamic when we were out in the field was that Herman Cain was ascendant. He had really grabbed the attention of the conservatives in the GOP primary race in particular. And we saw that reflected in this poll.”

Though they’re statistically tied — Cain’s lead over Perry is well within the survey’s margin of error — the former executive leads Perry among rural voters in Texas, and has a smaller lead among suburban Republicans.
