What's on TV?
Nobody really cares about politics and elections and all that crap. Most people are just glad to have all the talking heads off the box for a few years and have them make space for sports, Survivor and the really important stuff.
Walking down the street it is almost impossible to tell the difference between Clinton, Bush or Obama America. Most voters can't really tell their day to day policies apart and around 50% don't even vote.
A bit of fraud? Well who cares.... it would not have really impacted on the outcome. If the Diebold junk had caused the wrong person to be voted off the island then you can expect people to care.
