Obama can't be everything to everyone. He changed. He did. I never thought I'd hear Obama say, "Let's go back to nuclear arms," but he did. In the meantime, the clear and present danger is the Republicans in the Senate. A lot of politics isn't heroic, it's as day-to-day as our lives themselves. We always want to make the Byronic choices, but Byron himself was not Byronic all the time either.
