Awesome so far, though I'm not so sure King is as certain to caucus democrat as everybody seems to think. Especially if Mitt is elected.
In this climate, I don't see how he wouldn't caucus with the Democrats.
He claims he's undecided on who to caucus with, and if the unlikely GOP-wank scenario happens with 59 GOP senators, they'd be willing to give a good amount of nice committee seats to put them over the top (same if Obama's re-elected and the senate is 50-49 favoring the GOP, or if Romney is elected and the GOP has 49 seats) to put themselves over the top. Also, both were very nonpartisan governors (Mitt in MA, with a 75% Democratic legislature, and King with maybe a handful of Indy legislators)
