So is Sarah Palin really tapping into the id of the American public, ready to ride a wave of anti-Washington populism straight to 1600 Pennsylvania Avenue? The Washington Post's David Broder seems to think she might be, but his newspaper's numbers say different. Palin's favorability rating? Down six points since November. Her net favorable/unfavorable rating is now -18%. Is she qualified to be president? A stunning 71% say no. Even among the fabled base of conservative Republicans, only 45% consider her qualified. I guess that tea party speech didn't work out as well as she'd hoped.
