Our primary is already decided and the INCOMPETANT state GOP leadership pretty much made sure to it that none of the top-of-the-ticket races were contested. In the big 4 slots (senator, governor, lt. gov., and attorney general) the candidates were already chosen. Though Perry is the only really bad one out of that crowd, only one out of the remaining three is something to be excited about as a conservative. That's Greg Abbott, the AG nominee.
After Perry signed Hate Crimes, there was an effort from some of us trying to recruit Kay Bailey Hutchison to challenge him. That alone speaks volumes about Perry's non-conservative credentials, as Hutchison herself isn't exactly a right winger. I probably would have supported her though had she done it as the way things stand now, anything except for somebody from the John McCain or Arlen Specter wing of the party would look conservative next to Perry.
