FactCheck.org reports via Newsweek on the smear campaign assigned to posters like Vince and FUNdamental. When they post stuff that isn't supported with facts from credible news sources, you can reference this article and those like it.
Remember that people like Vince and FUNdamental are not interested in an educated electorate... they are cut from the cloth that is in favor of repeating things enough times to try to get people to believe them, such as "If the glove don't fit you must aquit!" and that kind of thing.
Certainly vote against McCain/Palin if you have policy differences with them as is your right and duty! But take everything the Vince/FUNdamental arms of the smear campaign post here for what it is.
During the primaries the Clinton campaign flooded our forums with anti-Obama smears such as the pics of him in the African garb, calling him a muslim, etc. It appears the Clinton operatives who orchestrated that are now working for Obama to take down Palin.
