Interesting that Putz hasn't mentioned one of his favorite Teabaggers leaving the Senate.
As for Jim, I'm not sure this is quite right. DeMint didn't leave the Senate because he'll have more power at Heritage, he left because a) he doesn't want any ownership of the looming BIGGEST TAX INCREASE IN HISTORY!11!; and b) he wants to get paid.
Holding office still matters. Just ask Sarah Palin.
