The GOP governor's primary in Texas still appears headed for a runoff, with the latest poll showing no candidate above 40 percent.

A new Public Policy Polling (D) survey shows that Gov. Rick Perry (R) appears to be a strong favorite over Sen. Kay Bailey Hutchison (R-Texas), but he'll likely need an extra month to finish the job. He leads her 40-31, while GOP activist Debra Medina is at 20 percent.

Medina is still very much a part of the dialogue, but it appears charges that she is a "truther" are hurting her candidacy. Her unfavorable numbers have climbed significantly in recent weeks (from 9 percent to 30 percent), but she actually holds a lead among those who don't think she is a "truther."

The primary is March 2, and the runoff would be April 13.
