Well, if Mike Huckabee really does see Texas as a firewall, it’s not looking good right now:
In the Texas Republican Presidential Primary, John McCain holds a modest eight-point advantage over Mike Huckabee. The latest Rasmussen Reports telephone survey of the race shows McCain earning 45% of the vote while Huckabee attracts 37%. Ron Paul is the choice for 7% and 11% are not sure.
Meanwhile, the ARG poll shows a slightly smaller 6 point lead for McCain.
