The Republican Party has a very strong affinity for the establishment candidate. He's the white brother who has been standing around on stage long enough, the patient vice president who is given the helm after sticking with the company through twists and turns.
There have been some mild exceptions. Reagan was not a complete outsider - he'd been around a couple of cycles, and he had a few powerful backers. But he came out of the West, from the ruins of the Goldwater effort. He represented a difficult, riskier direction in the brief period of time before he became an unstoppable force.
And Dubya was only establishment by birthright. But that was good enough in 2000, when he seemed to be the dependable alternative to the upstart Arizona senator who was giving him hell in the early part of the race. Winning the presidency back from the other party was a deadly serious a goal, and outsiders were not to be trusted.
How things have changed. McCain has been standing around long enough in the minds of the voting public, and he's charging forward to the nomination. Until Florida the conservatives could loudly protest that "real Republicans" hadn't yet voted. Now that argument has been kiboshed - not that there won't be second guessing.
The irony is that McCain has become the establishment candidate, and he did it simply by virtue of endurance and patience. Conservative disgust towards him will endure, but it may become an echo chamber discussion; wonks need to be reminded that the average voter thinks the "Gang of 14" is a martial arts movie, and they couldn't pick Sam Alito from a police lineup.
The other irony is that, with the benefit of hindsight, McCain 2000 might have been a much more attractive president through the 9/11 era. Personally, I'd much prefer the outsider then to the establishment guy today. But that's all water under the bridge.
Update: It's possible to construct a scenario where McCain becomes, for GOP hard-liners, a better alternative to staying at home. First, as everyone has said, nominate Hillary. That will help immeasurably. Second - credit Jonah Goldberg on 'Morning Joe' - McCain should clearly and consistently articulate some key promises on issues that are very important to the base. Border security ahead of anything else related to immigration, for example.
Yes, yes - nobody will believe him at first - he needs to say it repeatedly, and possibly have it tattooed on his arm. Another promise might be to really make the tax cuts permanent, which he has made noises about recently, but which again, nobody finds very persuasive. Finally a very shrewd VP pick ... and it
might be possible to win back a sizable enough portion of the base that will vote with the help of anti-nausea medication.
Let me add that I have a very hard time respecting Republicans who are taking the line "better to vote Democrat, so Hill or Obama gets the blame for the country going to hell". There's something about that that seems, to be honest, a little un-American, and I don't say that lightly.
We should vote for the right reasons, and we should support the candidate that we think is best for the country, or if you prefer, the least damaging. It's ultimately a serious responsibility - cleverness and resentment should stay outside of the voting booth. I don't want to see the United States of America go downhill regardless of who gets elected, and it's still our team, even if we don't like the current coach. And the Democrats might be gravely wrong on many issues, but they really don't want to destroy America, regardless of what you've been told - and I've even heard it whispered that some of them actually love their country. (Of course, civic, cultural and economic damage may be the net result of their policies - but that's something different.)
