Dan Sullivan will vote for passage because that's what Karl Rove and Charles Koch will tell him, via their Citizens United PACs, to do. Lisa will ultimately vote yes too, though she will make a better show of teetering, or get permission again to vote no (wink, wink) but not affect the outcome. She's less worried about future campaign funding, while Sullivan, were he to vote no, would risk being abandoned in favor of Joe Miller or other extreme right candidate.
