So... can we expect Susan Collins to "evolve" tomorrow or in the next few days? I mean come on. Gay marriage is already legal in Maine.
Personally, I doubt Collins will explicitly support same-sex marriage until after winning the GOP primary for her Senate seat next year. I'd imagine she's probably a bit paranoid about getting a primary challenge from a LePage type.
The Democratic Party of Maine sucks, though, and ballot access is easy in that state. Even if she did lose to LePage, she'd win the general as the Independent easily.
