What does her prominence say about the importance of having (or lacking) a record of achievement in public life?

Why did so many skilled veterans of the Republican Party - long regarded as the more adroit team in presidential politics - keep loyally working for her election even after they privately realized she was casual about the truth and totally unfit for the vice-presidency?

Perhaps most painful, how could John McCain, one of the cagiest survivors in contemporary politics - with a fine appreciation of life’s injustices and absurdities, a love for the sweep of history, and an overdeveloped sense of his own integrity and honor - ever have picked a person whose utter shortage of qualification for her proposed job all but disqualified him for his?

McCain has delivered his own postmortem on Palin with the patented brand of winking-and-nodding ironic detachment that he usually reserves for painful political questions, an approach that simultaneously seeks to confess his sin and presume absolution for it. In November, he told Jay Leno he was proud of Palin and did not blame her for his defeat, but by April, when Leno asked him about who was running the Republican Party, McCain declined to mention Palin: “We have, I’m happy to say, a lot of choices out there: Bobby Jindal, Tim Pawlenty, Huntsman, Romney, Charlie Crist—there's a lot of governors out there who are young and dynamic.” McCain went on, “There’s a lot of good people out there, and I’ve left out somebody’s name and I’m going to hear about it.” When I ask Mark Salter, McCain’s longtime speechwriter and co-author, about that comment, he says simply, “McCain always talks unscripted,” and adds that he has heard “not one word of regret” about Palin ever pass McCain’s lips. McCain’s daughter Meghan, who has continued the blog she began on the campaign last year, has said that Palin is the one topic on which she will have no public comment. [my emphasis]

Some top aides worried about her mental state: was it possible that she was experiencing postpartum depression? (Palin’s youngest son was less than six months old.) Palin maintained only the barest level of civil discourse with Tucker Eskew, the veteran G.O.P. operative who had been made her chief minder. A third party had to shuttle between them to convey even the most rudimentary messages. "She started to hedge her bets," the same McCain friend says. "Frequently, she would be concerned about how something would play in Alaska. What? You’re worried about your backside in Alaska when there are hundreds of millions of dollars being spent?" One longtime McCain friend and frequent companion on the trail was heard to refer to Palin as "Little Shop of Horrors."

More than once in my travels in Alaska, people brought up, without prompting, the question of Palin’s extravagant self-regard. Several told me, independently of one another, that they had consulted the definition of “narcissistic personality disorder” in the Diagnostic and Statistical Manual of Mental Disorders — “a pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy” — and thought it fit her perfectly. When Trig was born, Palin wrote an e-mail letter to friends and relatives, describing the belated news of her pregnancy and detailing Trig’s condition; she wrote the e-mail not in her own name but in God’s, and signed it “Trig’s Creator, Your Heavenly Father.” [my emphasis]

The symptoms of narcissistic personality disorder revolve around a pattern of grandiosity, need for admiration, and sense of entitlement. Often individuals feel overly important and will exaggerate achievements and will accept, and often demand, praise and admiration despite worthy achievements. They may be overwhelmed with fantasies involving unlimited success, power, love, or beauty and feel that they can only be understood by others who are, like them, superior in some aspect of life.

There is a sense of entitlement, of being more deserving than others based solely on their superiority. These symptoms, however, are a result of an underlying sense of inferiority and are often seen as overcompensation. Because of this, they are often envious and even angry of others who have more, receive more respect or attention, or otherwise steal away the spotlight. [my emphasis]

Palin’s victory that November was one of the flukiest successes in modern American politics. Rebecca Braun, the publisher of the Alaska Budget Report, a respected nonpartisan newsletter, describes the result as something "far beyond anything you could explain in terms of intellect or training." But Palin had promised three big things, and with the help of Bitney, who became her liaison with the legislature, and Mike Tibbles, her chief of staff, she achieved them. She increased oil taxes; she won the legislative framework for a gas pipeline, though not the one Hickel wanted; and she signed significant ethics reforms. In all three efforts she won strong cooperation from Democrats. “She had an easy go of it,” says Larry Persily, a former editorial-page editor of the Anchorage Daily News, who went to work in Palin’s Washington office but is now a critic of the governor’s. “The Democrats were in love with her. She slew the oil-company Gorgon, and came in on the magic carpet of oil-tax reform and ethics. The Democrats were intoxicated because she wasn’t Frank Murkowski.” Rising oil prices provided an added lift. Palin was able to increase the annual distribution from the state’s Permanent Fund to about $3,000 per resident, almost double the amount received the previous year. She could be a fiscal conservative and a big spender all at the same time.
