Obama on Verge of Shift on Marriage Equality?

It sure sounds like it, judging by his exchange with AMERICAblog's Joe Sudbay during a sit down with liberal bloggers today at the White House. Here's President Obama's response to a question about his position on same-sex marriage (after some back-and-forth):

THE PRESIDENT: I think it’s a fair question to ask. I think that -- I am a strong supporter of civil unions. As you say, I have been to this point unwilling to sign on to same-sex marriage primarily because of my understandings of the traditional definitions of marriage.

But I also think you’re right that attitudes evolve, including mine. And I think that it is an issue that I wrestle with and think about because I have a whole host of friends who are in gay partnerships. I have staff members who are in committed, monogamous relationships, who are raising children, who are wonderful parents.

And I care about them deeply. And so while I’m not prepared to reverse myself here, sitting in the Roosevelt Room at 3:30 in the afternoon, I think it’s fair to say that it’s something that I think a lot about. That’s probably the best you’ll do out of me today.

That first sentence of the second paragraph -- and "attitudes evolve, including mine" -- certainly make it sound like the President wants to change his public position on marriage equality, even if not now. Of course this isn't going to sate those working hard across the country on the issue. But inasmuch as this is the first time the President has been pressed on the issue in some time (as best I can tell), it may send a signal to those who care deeply about the issue that change is going to come.
