Here is Christopher Buckley's take on the matter:
A year ago, when everyone, including the man I’m about to endorse, was caterwauling to get out of Iraq on the next available flight, John McCain, practically alone, said no, no—bad move. Surge. It seemed a suicidal position to take, an act of political bravery of the kind you don’t see a whole lot of anymore.
But that was—sigh—then. John McCain has changed. He said, famously, apropos the Republican debacle post-1994, “We came to Washington to change it, and Washington changed us.” This campaign has changed John McCain. It has made him inauthentic. A once-first class temperament has become irascible and snarly; his positions change, and lack coherence; he makes unrealistic promises, such as balancing the federal budget “by the end of my first term.” Who, really, believes that? Then there was the self-dramatizing and feckless suspension of his campaign over the financial crisis. His ninth-inning attack ads are mean-spirited and pointless. And finally, not to belabor it, there was the Palin nomination. What on earth can he have been thinking?
All this is genuinely saddening, and for the country is perhaps even tragic, for America ought, really, to be governed by men like John McCain—who have spent their entire lives in its service, even willing to give the last full measure of their devotion to it. If he goes out losing ugly, it will be beyond tragic, graffiti on a marble bust.
Like me, Buckley has long been a McCain booster and is deeply disappointed to see what the McCain campaign has become.
I've been even more heartbroken as I've worked my way through Bing West's "The Strongest Tribe," in which West frequently cites Senator McCain's work in bringing the Bush administration about with regard to troop levels and tactics in Iraq.
Here is what Buckley says about Obama:
As for Senator Obama: He has exhibited throughout a “first-class temperament,” pace Oliver Wendell Holmes, Jr.’s famous comment about FDR. As for his intellect, well, he’s a Harvard man, though that’s sure as heck no guarantee of anything, these days. Vietnam was brought to you by Harvard and (one or two) Yale men. As for our current adventure in Mesopotamia, consider this lustrous alumni roster. Bush 43: Yale. Rumsfeld: Princeton. Paul Bremer: Yale and Harvard. What do they all have in common? Andover! The best and the brightest.
Buckley's sentiments are echoed by Christopher Hitchens:
I suppose it could be said, as Michael Gerson has alleged, that the Obama campaign's choice of the word erratic to describe McCain is also an insinuation. But really, it's only a euphemism. Anyone with eyes to see and ears to hear had to feel sorry for the old lion on his last outing and wish that he could be taken somewhere soothing and restful before the night was out. The train-wreck sentences, the whistlings in the pipes, the alarming and bewildered handhold phrases—"My friends"—to get him through the next 10 seconds. I haven't felt such pity for anyone since the late Adm. James Stockdale humiliated himself as Ross Perot's running mate. And I am sorry to have to say it, but Stockdale had also distinguished himself in America's most disastrous and shameful war, and it didn't qualify him then and it doesn't qualify McCain now.
Like me, Hitchens does not suppose Obama will be a panacea:
I used to call myself a single-issue voter on the essential question of defending civilization against its terrorist enemies and their totalitarian protectors, and on that "issue" I hope I can continue to expose and oppose any ambiguity. Obama is greatly overrated in my opinion, but the Obama-Biden ticket is not a capitulationist one, even if it does accept the support of the surrender faction, and it does show some signs of being able and willing to profit from experience. With McCain, the "experience" is subject to sharply diminishing returns, as is the rest of him, and with Palin the very word itself is a sick joke. One only wishes that the election could be over now and a proper and dignified verdict rendered, so as to spare democracy and civility the degradation to which they look like being subjected in the remaining days of a low, dishonest campaign.
In other news, Obama appears poised for a blowout. I'd say 100+ electoral points is realistic at this point.
