The reason Cornyn has been voting with Cruz so much is that he wants to make sure Cruz doesn’t seek an alternative candidate for 2014 for the Cornyn seat. It’s all a sham though. If there is to be an alternative candidate, he must be found within the next six months. Wait until 2015, when Cornyn resumes his lurch to the left. John Tower used to vote conservative two years before his elections too; it’s a trick TX Republicans cannot grasp.
I hope a good conservative turns up to run against Cornyn, within the next six months. (Maybe Michael Williams?)
