A Texas Tribune poll has Davis down by around 6 points depending on how well the Libertarian candidate is polling. 6 points is not a bad place to be a year out, of course I have my doubts that she will win, but I believe she will lose with the closest margin since 1994. I believe this will turn into a tighter race then Texas is use to seeing.
I agree, and I think the retirement of Gov. Perry is ultimately the cause. So many of the poll results that were surprising me pointed to the land rush for every state-wide office in the state (on the GOP side). At the Governor's level, of course, this is the first open election since 1990.
