also, you must remember that back when Palin debuted on national stage, her approval was like 41%, and right before the VP debate, 26%-ish. That means 26% were teh neocons, and the extra 18-20% were unsure undecided voters who were attracted to Palin for the sole reason taht she was a white squeaky clean mom whose name doesn't rhyme with Yo Mama. What tha ttells me is 20% or so who are undecided moderates are so unintelligent that they would be swayed by 'liberal' pro-obama coverage, or palin appearing cute and primpy like in the debate. So again: do not underestimate the effect of the GOP strategy.
and to those who are so sure obama will win: there's still a month left. I remember when in 04, bush practically flunked the first debate, bullied the mod on teh second one, and came away with a 'draw' on the third one [by 'draw', i mean by the war of perception and style, not substance]. Of course, back then the times were more fearful and phobic, but still...the man won.
So don't make too many assumptions.
