They had sparred repeatedly up until very recently, but Mitt Romney, who ended his presidential bid last week, endorsed John McCain at an event in Boston this afternoon.
Those past disagreements are almost certain to be glossed over later this afternoon when Romney offers his seal of approval for McCain. But given the animosity between the men, why is Romney endorsing? And what does it mean for the race?
The first question is the easier to answer. Romney clearly believes he has a bright political future and wants to make sure he is seen by rank-and-file Republicans as a loyal footsoldier for the cause, not a self-centered whiner. By standing with McCain, Romney shows that the primary race is water under the bridge (even if he really doesn’t believe that) and that he is putting the good of the party before his own self interest. (The move is not dissimilar to McCain’s work to elect and reelect George W. Bush following his own bitter loss in 2000.) It’s the first major step to a second Romney presidential bid in either 2012 or 2016.
That’s all true, of course, but I think there’s a practical angle that’s just as significant. Romney earned 286 delegates during his campaign, and he wants them all to go to McCain. Given that the Arizona senator started the day with 827, he’ll now have 1,113 delegates.
The “magic number” at which McCain formally clinches the nomination is 1,191, meaning that Huckabee would have to win practically everything between now and the end of the nominating process to prevent McCain from getting the party’s nod.
Since that isn’t going to happen, Romney’s support effectively seals the deal and ends the race. We knew that, of course, but as of this morning, McCain was still saying of the former Arkansas governor, “Of course, I would like for him to withdraw today; it would be much easier.” As of this afternoon, it’s easier anyway.
