I think it'll help him.
Yes, it will alienate some voters, but I feel as though it will strengthen the support and loyalty from others. I doubt that many people extremely against same sex marriage were seriously thinking about supporting him anyway. Those on the fence will have a choice to make just like they did last time.
He knows it's campaign season. His campaign managers, advisers, political analysts, publicist, and everyone else employeed by the White House know this as well. I'm sure they carefully decided to announce this and have done plenty of studies, polls, etc on the outcome.
