I have followed (like others) what is going on in DE, I am not convinced the there is a spin that she is as you said “stupid” abd she has “baggage.” I do not see anything suggesting her opponent is any smarter. I know some very smart people who bought into the Palin is dumb spin and still believe it.
Democrats don't have to be smarter than us because they have the media running interference for them. But she does have some serious baggage.
First there's the lawsuit against ISI, which is an old guard Goldwater-Reagan style conservative think tank, despite the association of this charge with Rove. Second, she engaged in some pretty serious fibbing about her college credentials on her resume. Third, she's got the type of financial history that would scream out "Community Reinvestment Act" were she not a white Republican.
