Why davka Palin? Why not Snowe? Or Lingle?
I hadn't heard of Sarah Palin before McCain's announcement, nor had I heard of Snowe and Lingle (I'm not so beki'ah on the governors and senators of all the states; I'd have to memorize them all).
Snowe is considered a moderate Republican and apparently has a 79% approval rating from her constituents, so she must be doing something right.
Lingle was elected as Governor of Hawaii in 2002 and is now serving her second term of office. She has an approval rating of 71% of her constituents. And she's Jewish.
Wait, I know--Neither of them was Miss Maine or Miss Hawaii. That must be it. . .
