In addition to being merely having been, as Steve Benen pointed out, "...the governor of a small state for a year and a half, and who is in the midst of an abuse-of-power investigation in which she appears to have lied rather blatantly. She has no obvious expertise in any area, and no record of any kind of federal issues. McCain doesn't care." Now we learn that Sarah Palin and her husband were Brigadiers for Pat Buchanan in 1996. Although Pat Buchanan denies being anti-Israeli or anti-Semetic, he has his own page at the Anti-Defamation League web site.
In 1996 Pat Buchanan ran for President because Bob Dole was not nearly conservative enough to suit him. This is the man Sarah Palin and her husband supported.
The choice of Sarah Palin as McCain's running mate is a guarantee that McCain is running to fill Bush's third term and to push the country further to the right than even Bush and Cheney did in the first two terms.

It appears that contrary to the statements put out from the McCain camp, there was very little vetting of Sarah Palin before McCain announced her as his choice for Veep. The McCain Camp Didn't Search Palin's Hometown Paper Archives. The article also reminds us that
...the McCain campaign did not contact Public Safety Commissioner Walt Monegan, who Palin pushed to have fired after he refused to remove her sister's former husband from the state's police force. [Snip]It is this kind of impulsive judgment that characterizes John McCain. He expects the American voters to elect him President at age 72 and a cancer survivor and to give the job of his replacement if he dies or becomes disabled to a beauty queen that he choose after meeting her only three short times and with almost no vetting at all? That's noting short of political malpractice.
In addition, the former Republican House Speaker of Alaska, Gail Phillips, admitted to reporters that she was shocked by McCain's choice of Palin, as "his advance team didn't come to Alaska to check her out."
Even McCain's own aides seemed unprepared by the choice. After Palin's name was announced, spokeswoman Nancy Pfotenhauer was asked about the governor's relationship with the Senator.
"You're running flat into the wall of my ignorance here," she said. "I truly have no indication whatsoever the extent of a relationship that exists with the Governor of Alaska."
