"He's backtracking because he didn't expect so many people to disagree with him."
I think that's Mark Hanson's point. McCain wouldn't have apologized in the past because few would have known what he's talking about, much less disagree with him. The fact that he felt he should apologize, regardless of the reason or sincerity, shows that this movement has grown to be a force that McCain and the neocons can't just ridicule or ignore any more.
