If those in the Democratic and Republican parties voted based upon integrity last presidential election wouldn't have been McCain vs. Obama it would have been Ron Paul vs. Dennis Kucinich.

They give all the time and attention to their darlings and they only ask token questions to the candidates that offer a real change and subtly try to sabotage them. They asked Democrat Dennis Kucinich in a presidential debate in 2008 whether he saw a UFO for no other reason than it would make people think the guy was loony.
