We've got some fascinating polling data looking at the GOP primary race through the prism of the federal military takeover of Texas, separating out "takeover" voters (who believe the federal government is trying to take over Texas) and "squishes" (who are taking the Pentagon's word for it that the takeover isn't happening). Among "Takeover" voters the top choice is Scott Walker. For "Squishes", it's Jeb Bush.
The two candidates with the highest percentage of takeover voters are Rick Perry (76%) and Ted Cruz (56%). That's the percentage of their supporters who are "takeover" voters.
