Andy Stern Resigns SEIU – Where is he headed?

Politico reports the news with little else but Stern’s purple-pleasing accomplishments:

The SEIU has emerged as a central political player and has grown rapidly under Stern’s tenure, and some close to him had expected him to resign during the first term of the president he helped elect. But he’s also waged a series of bitter battles inside the labor movement, one of the nastiest of which turned in SEIU’s favor with a California court ruling last week. Stern also won a victory when Obama named his union’s lawyer, Craig Becker, to the National Labor Relations board over Republican objections in a recess appointment last month.

Stern, even without the union presidency, would remain on, among other things, the board of President Obama’s deficit commission, to which he was appointed in February.

It makes me physically ill to think he will sit on the deficit commission. This alone confirms the domestic agenda is not an accident. So, who has a theory about this resignation?
