The Republican big-wigs are falling all over themselves blaming each other for the Palin fiasco. Nothing like building party unity for winning the next election through no-holds barred, bare knuckle fighting each other in public.

A hard-hitting piece on Sarah Palin in the new Vanity Fair has touched off a blistering exchange of insults among high-profile Republicans over last year’s GOP ticket – tearing open fresh wounds about leaks surrounding Palin and revealing for the first time some of the internal wars that paralyzed the campaign in its final days.

Rival factions close to the McCain campaign have been feuding since last fall over Palin, usually waging the battle in the shadows with anonymous quotes. Now, however, some of the most well-known names in Republican politics are going on-the-record with personal attacks and blame-casting.

So what is Palin up to? From the fascinating Vanity Fair article:

In the aftermath of the November election, the conventional wisdom among Palin’s supporters in the Republican establishment was that she should go home, keep her head down, show that she could govern effectively, and quietly educate herself about foreign and domestic policy with the help of a cadre of experienced advisers. She has done none of this. Rather, she has pursued an erratic course that, for her, may actually represent the closest thing there is to True North. [...] She created a political-action committee—Sarahpac—with the help of John Coale, a prominent Democratic trial lawyer. But just months into its existence the pac’s chief fund-raiser, Becki Donatelli, a veteran of Republican campaigns, suddenly quit. One person familiar with the situation told me that Donatelli could not stand dealing with Palin’s political spokeswoman in Alaska, Meghan Stapleton, who has drawn withering fire from Palin friends and critics alike for being an ineffective adviser. Also with Coale’s help, Palin formed the grandiosely named Alaska Fund Trust, to defray a reported half million dollars in legal expenses arising from a slew of formal ethics complaints against her in her home state—prompting yet another formal complaint, that the fund itself constitutes an ethical breach. Onetime supporters have become harsh critics. Walter Hickel, 89, a former two-term governor and interior secretary, and the grand old man of Alaska politics, who was co-chair of Palin’s winning gubernatorial campaign, in 2006, now washes his hands of her. He told me simply, “I don’t give a damn what she does.”

And on and on… So, do you think Palin will run for Prez in ‘12?
