Expectation of Corruption
OK- this is from Opednews.com: they did a poll in penna. but it is their interpretation that is very interesting:

"If you add up the percentage of Republicans who say that Republicans are corrupt and both parties are corrupt you get a total of 77% of Republicans saying that Republicans are corrupt, compared to 15% of Democrats saying Democrats are corrupt. What does this mean? Republicans assume their representatives are corrupt because they think everyone is corrupt. That's the mindset of a culture of corruption. They see they world as corrupt and they accept it."
