Most of these scandals don't matter. What matters is that Palin is suffering from the same sort of scandal of the hour syndrome that George Allen fell victim to, which means the very existence of scandal encourages the media to dig for more "scandalous" stories regardless of whether they matter or not. In turn, most Americans will simply note that she had another scandal without analyzing it because its what they have been led to expect from her. This is really bad, and its hard to break this narrative once it has you. Its one reason why I don't think she will last. After today, even the most minor thing will be blown all out of proportion.
True. How many threads about her compared to threads about Biden?
Palin was an attention grabbing pick. That worked both in favor of the McCain campaign(by distracting attention from Obama's speech) and against it(by making Palin the issue). What determines whether or not this was smart will be whether that increased attention is positive or not.
Palin(and McCain's) problem is that the determination of that is not really under their control. No one believed Biden had any scandals that had not come out yet, so the national media did not descend on Delaware after he was picked. A couple bad stories got leaked about Palin, and the media descended on Alaska. Its now come out that the reason the Bristol story was released had nothing to do with DailyKos and everything to do with the fact that the National Enquirer was about to break it. The problem for Palin is every story the media digs up convinces the diggers that there is more to find.
