and to be fair - I think Palin is pretty bright too. She knows how to manipulate situations, form networks, and build some pretty powerful relationships.
She's just not well-versed in things like history or the economy - things that a president should be very good at. Obama knows law, there is no denying that, and he did spend 5 years touring the world on the foreign relations committee in congress, so he was somewhat good there. He had no economic skills - and we're seeing that now
he just kept the old money guys in charge and did whatever they said while punching thru a clinton stimulus.
So I don't want to just kneepad obama here - most people at the top level of politics are pretty bright. Pelosi (whom I disagree with on nearly everything) is very bright. Mitt and Rudy and yes, Mccain are very bright. Edwards is not that bright, neither is fred thompson.
misguided and 'dumb' are tricky terms. You can be naive to fall for a misguided political views - and be a smart person the whole time. Hell, I tested 137 IQ through grade school and got an MBA without too much study, and I'm quite the political dumbass, right?
