Cruz’s 25 percentage-point lead over Walker in October has vanished: The Texan won the support of 20 percent of the state’s registered voters to Walker’s 19 percent — a statistical tie. Former Florida Gov. Jeb Bush and author Ben Carson were tied at 9 percent, and former Texas Gov. Rick Perry was next at 8 percent.

“Scott Walker is clearly breathing some of the oxygen on the right. The big takeaway here is that Ted Cruz is still a giant among Texas Republicans — but he is not invulnerable,” said Jim Henson, co-director of the poll and head of the Texas Politics Project at UT-Austin. “Conservatives are willing to look at another candidate who fits that profile.”

In the October UT/TT Poll, Cruz registered 27 percent of the support to Walker’s 2 percent. Perry, now running fifth, was running second a few months ago.
