Nonsense. Never before in my lifetime has the average American been more aware of how much the actions of government effect their lives and their future. People don't like the way things are and they think government has caused it. They will get out to vote for change.
Same here. People stay away from stuff they don't like, or are resigned about. For example, the story line for Conservatives is that the MIttbots, people who have no discernible ideology nor core beliefs, are telling them that they should get over it and vote for Mitt because the other guy is so much worse.
Yet the other guy seems to have virtually the same beliefs as Mitt.
It is entirely reasonable to abstain from making a choice between bad and bad.
