There can’t be too many who haven’t seen through Sarah Palin by now. She’s a conniving, under-educated opportunist, living in a walled-off realm and out for whatever money and power she can grab by playing the part of a right-wing Annie Oakley bigmouth (and sex symbol). It’s good to hear nonetheless that Nick Broomfield has been working on a presumably anti-Palin documentary, and that the negligible political effect of The Undefeated (which will open exclusively at several hinterland AMC theatres on 7.15) will be counterbalanced to some extent. The Broomfield doc was written about last night by L.A. Times Stephen Zeitchik.
