Good move, regardless of his motivations. By 2016 there will be plenty of time to "walk it back." I think he's probably more concerned with shoring up a now almost certain re-election.
There's no way to show efficacy if a practice is banned. The thing about these types of laws, they don't just ban methods of therapy, some of which are abusive. They ban aims of therapy - which comes awfully close to the government inserting itself in between the therapist-patient relationship. If the standard is the government is going to ban anything that hasn't been proven to be effective, then the practice of clinical psychology is going to be severely limited.

You think a majority of the Pubs favor gay conversion "therapy?"
Sure wouldn't surprise me if a slim majority of GOP
primary voters do. But of course that's an overall demographic that I'm not terribly optimistic about. And I would bet that they think it's a "sin," whatever that can mean in the present.
