What follows this post are two intelligent pieces on Palin, one from 'the Right' (City Journal), another from 'the Left' (The New Republic, a partial).
[Note: given the diversity that falls under those labels, I think they're both virtually meaningless, except as very loose approximations. (See my "Are You a Socialist" test.) But we have to call them something.]
Both are judicious and fair minded. That is, after all, how political debate is supposed to be (but rarely is) carried on.
