Wexler Departure Perplexing

Just when Alan Grayson is starting to make the Florida Congressional delegation look a little bit better, the best legislator the state has to offer, Rep. Robert Wexler, announces he's retiring from Congress in January to lead the Center for Middle East Peace and Economic Cooperation.

Now I'm all for a think tank beneficial to the situation in the Middle East, in fact I plan to monitor their website for employment opportunities, but this is a progressive Democrat with courage--among the rarest commodities in all of American politics. Only sensible Republicans are more rare. And he's walking away to run a think tank?

I really hope there's no other shoe poised to drop here. No reason to think the worst about such a good politician, but he is a politician. TPM offers up several possible reasons why Wexler is walking.
