Senate Passes Keystone XL Pipeline, Obama Threatens Veto

So far, the dirty hands
are not the President's

So... which of the President's desired shiny objects will he trade that veto for? You know that's going to happen: Keystone XL is a done deal, but Mr. Obama is a politician of some skill. For what, precisely, will he trade his signature, the favor the fossil fuel industry desires, probably the dirtiest pipeline ever proposed? Or will the GOP-ruled Congress take the choice out of the President's hands altogether by attaching the bill to some must-pass legislation?

DSWright and a lot of the regular commenters at FDL discuss the possibilities. Here's a hint: the possibility that Obama really means to veto and make it stick is not seriously discussed.
