This reveals a lot:
Perry is struggling to answer a question about why a commitment to abstinence education makes sense when Texas has the third highest teenage pregnancy rate in the country. Shorter Perry — it works because I say it does. Also he has personal experience with abstinence. Right. See also Steve Benen and Paul Wildman.
In more Perry news — Bruce Bartlett called Perry an idiot. Yes, but he’s a ruthless idiot.
Update: See Ezra, “How much did illegal immigrants contribute to Texas’ economic boom?” Quite a bit, it seems.
