Ohio Sen. Rob Portman’s announcement that he had decided to give up his opposition to gay marriage — a decision prompted, at least in part, by the fact that one of his sons is gay — is the latest in a series of moves that make one thing crystal clear: The political debate on gay marriage is effectively over. Portman is a pillar of the political establishment – he held two different Cabinet posts in George W. Bush’s Administration – served in the House, and was widely mentioned as a potential vice presidential pick. That someone with his profile — his own personal circumstances notwithstanding — would reverse positions in such a high-profile way tells you much about how the politics of the issue are shifting.
