Barack Obama - Disapprove - 43.2%
(with 52.2% approve)
Sarah Palin - Not favorable - 38%
(with 23% favorable, 20% undecided, 17% haven't heard enough, and 2% refused)
You'd never guess it from the media coverage, but Obama seems to have a higher negative than Palin. Plus, Palin's not responsible for 17.5% (and rising) real unemployment.
They attack her and mock her because they fear her.
