If Abbott ends up supporting anyone other than Ted Cruz he’s a fool.
The profile is worth reading in its entirety.
...when Greg Abbott became attorney general of Texas, in 2002, he decided to expand the responsibilities of the solicitor general beyond simply handling appeals in cases involving the state. Abbott had served on the Texas Supreme Court and developed strongly conservative views on legal issues. I wanted someone who had the capability to handle appellate arguments in court, but I wanted to do so much more, Abbott told me. I wanted Texas to be a national leader on the profound legal issues of the day. I wanted us to be able to have a larger footprint, a larger impact.Though Cruz was only thirty-two, he persuaded Abbott that he was up to the job. In 2003, he moved to Austin. We wanted Ted to take a leadership role in the United States in articulating a vision of strict construction. I look for employees with batteries included, Abbott said. Ted was supercharged and ready to go. In effect, he asked Cruz to roam the country in search of cases that might advance the Constitutional agenda that Cruz had first embraced as a teen-ager. Sometimes Texas was an actual party to the cases Cruz argued, and sometimes he simply volunteered to write friend-of-the-court briefs for causes that he and Abbott supported. They intervened in cases supporting gun-owners rights, states rights, and the right to religious expression in public places.
