The Bushies have never been supporters of Cruz...supported his opponent when he ran for the senate.
BTW, I supported Cruz for the senate and now I can't stand him!
Before Cruz ever heard of Goldman Sacks, while still in high school, he and some friends memorized the Constitution and went around Texas making speeches on it to civics clubs. Of course since then he went to Harvard.
He has done a good job as Solicitor General of Texas.
