If Obama endorsed same sex marriage, would it help his campaign?

[The world will shine with light in our nightmare]

Personally, I've spoken to a few liberal Third Party supporters who say that Obama's silence on the issue partially influenced their decision not to vote for him this time around, so it would definitely help rally the base at least somewhat.  And as the country becomes more friendly toward the issue, less people are going to be basing their votes on that one issue and vote for the Republican, especially since social issues are the last on voters' minds today.  It would also make him look more like a person who's honest about the way they feel rather than someone who just follows what the polls say like Romney is.  So overall, I would say a significant net positive... but definitely not enough to guarantee him reelection.

Gay marriage is just no longer a toxic issue for Democrats that would have a huge impact, at this point.
