That ideological sellout, unfortunately, was not the worst leadership trait the last-minute vice presidential pick revealed about McCain. His speed-dating of Palin reaffirmed a more dangerous personality tic that has dogged his entire career. His decision-making process is impetuous and, in its Bush-like preference for gut instinct over facts, potentially reckless.

As The New York Times reported last Tuesday, Palin was sloppily vetted, at best. McCain operatives and some of their press surrogates responded to this revelation by trying to discredit The Times article. After all, The Washington Post had cited McCain aides (including his campaign manager, Rick Davis) last weekend to assure us that Palin had a “full vetting process.” She had been subjected to “an F.B.I. background check,” we were told, and “the McCain camp had reviewed everything it could find on her.”

The Times had it right. The McCain campaign’s claims of a “full vetting process” for Palin were as much a lie as the biographical details they’ve invented for her. There was no F.B.I. background check. The Times found no evidence that a McCain representative spoke to anyone in the State Legislature or business community. Nor did anyone talk to the fired state public safety commissioner at the center of the Palin ethics investigation. No McCain researcher even bothered to consult the relevant back issues of the Wasilla paper. Apparently when McCain said in June that his vice presidential vetting process was basically “a Google,” he wasn’t joking.

This is a roll of the dice beyond even Bill Clinton’s imagination. “Often my haste is a mistake,” McCain conceded in his 2002 memoir, “but I live with the consequences without complaint.” Well, maybe it’s fine if he wants to live with the consequences, but what about his country? Should the unexamined Palin prove unfit to serve at the pinnacle of American power, it will be too late for the rest of us to complain.

We’ve already seen where such visceral decision-making by McCain can lead. In October 2001, he speculated that Saddam Hussein might have been behind the anthrax attacks in America. That same month he out-Cheneyed Cheney in his repeated public insistence that Iraq had a role in 9/11  even after both American and foreign intelligence services found that unlikely. He was similarly rash in his reading of the supposed evidence of Saddam’s W.M.D. and in his estimate of the number of troops needed to occupy Iraq. (McCain told MSNBC in late 2001 that we could do with fewer than 100,000.) It wasn’t until months after “Mission Accomplished” that he called for more American forces to be tossed into the bloodbath. The whole fiasco might have been prevented had he listened to those like Gen. Eric Shinseki who faulted the Rumsfeld war plan from the start.

In other words, McCain’s hasty vetting of Palin was all too reminiscent of his grave dereliction of due diligence on the war. He has been no less hasty in implying that we might somehow ride to the military rescue of Georgia (“Today, we are all Georgians”) or in reaffirming as late as December 2007 that the crumbling anti-democratic regime of Pervez Musharraf deserved “the benefit of the doubt” even as it was enabling the resurgence of the Taliban and Al Qaeda. McCain’s blanket endorsement of Bush administration policy in Pakistan could have consequences for years to come.
