That’s a good theory. The other I heard was that he’s trying to angle for a Senate seat from Texas.
...Which is weird because he bounced Kay Bailey Hutchison from being the Governor. I’m sure that if each wanted the other’s job, they could have made an agreement for one to endorse the other for the gig.
He’s just running on pride, right now. This campaign will hurt him in Texas, and there is really no place for him to go. Texas is electing a new senator this year and I doubt he will displace Cornyn.
