David Boaz dismisses Palin's chances in 2012:
One of the standard defenses of Palin is “liberals said Reagan was dumb.” Yes, they did, even after he out-debated Bobby Kennedy in an internationally televised debate just months after he became governor. Democratic mandarin Clark Clifford, who didn’t realize that the bank he chaired was run by actual criminals, famously called Reagan an “amiable dunce.” But now that Reagan’s hand-written radio commentary scripts have been published, no one really makes this claim any more. Read Reagan in His Own Hand, read the commentaries he wrote on yellow pads while being driven from Los Angeles to Santa Barbara, and ask yourself: Could Sarah Palin do that?
