From what little of Palin I know thus far, she seems to be about as good a pick from a major party as libertarians could hope for. But how McCain picked her is a bit disconcerting:

Sarah Palin pumps her fist as she is introduced to supporters at a campaign rally in Dayton, Ohio, Friday.

John McCain on Friday announced a running mate whom he met only six months ago and with whom he spoke just once on the phone about the position before offering it in person earlier this week.

McCain's first encounter with Sarah Palin came at a Washington meeting of the National Governors Association in February, according to a campaign-provided reconstruction of how the little-known Alaska governor was thrust into the national spotlight. The two discussed the position by phone on Sunday before McCain invited Palin and her husband to Arizona to formally make the offer. McCain, joined by his wife, Cindy, did just that Thursday morning at their home near Sedona, Ariz.

By picking somebody he and most Americans barely know — an out-of-the-blue decision that sent shock waves of disbelief through the political world and still has jaws agape — McCain has taken a considerable gamble.

I don't buy the "no experience" critique. Frankly, I'd rather have someone in the White House who hasn't been corrupted by too much time in politics. I do wonder though, why McCain has so much confidence in Palin after spending so little time with her. It certainly can't be her record–there's not much to go on there, either.

They cynical (and probably correct) answer would be that pretty, female, and social conservative were all he needed. That is, his main concern was how she could help him win, not so much how well she'd do in the no-so-unlikely event that she were to become president.
