I too know Ted, who's running for Texas Attorney General, and think very highly of him: He is extremely smart, an "outstanding advocate" (as Orin notes), and in general the very sort of serious, accomplished, and highly professional lawyer that I wish we had more of in elected politics. (As Orin points out, he clerked for Chief Justice Rehnquist, has served as Texas Solicitor General, and is now the head of the Morgan Lewis appellate practice.)
Ted's views are more solidly conservative than mine. But I would have gladly voted for him if I were a Texan; not being a Texan, all I could do was contribute to his campaign, and I would encourage others to do the same.
UPDATE: Prof. Rick Garnett (Mirror of Justice) writes:
My friend and co-clerk (with Chief Justice Rehnquist), Ted Cruz, is running for Attorney General (he served for several years as the state's Solicitor General), as a Republican, in Texas. Ted is -- no surprise, for a Republican running in Texas -- a conservative, and he and I have not always seen eye-to-eye on policy matters (including capital punishment. MOJ readers in Texas should know, though, that -- besides being a stalwart friend and a prince among men -- Ted is solid as a rock, and inspiringly passionate, when it comes to school choice and education reform. In fact, the first conference I ever organized I organized with Ted. It was a big event, in Ohio, which dealt with the social-justice and religious-freedom aspects of the school-choice issue. To have such a committed advocate, on such an important matter, in the AG's office, in one of the largest states, would be a very good thing.
I remember that conference, too, and I remember how forceful and effective Ted's speech on the subject was. I think that was only the second time I'd met Ted, and it made me think that here was a man who was going to go far -- which he is indeed doing.
