Ed Kilgore tests the governor's weak spots:

[W]hile Perry has become a Tea Party favorite, he has done so in part by making inflammatory statements that may trouble even a healthy number of Republican primary voters, the most famous of which was his suggestion that secession might be on the table for Texas. In addition, he’s also made threats to withdraw the state from the Medicaid program—with only the vaguest suggestion of how or whether poor families would receive medical treatment—and even sought the power to opt Texas out of Social Security, a rather egregious stomping on the third rail of politics.

PPP finds that Perry has very low home-state primary support.
