I think the key here is the Republicans tend to believe that there's a lot of self responsibility. Democrats believe that there's a lot of state responsibility.
I know a lot a small business people who are Republican. Very few are Democrat. That's just the way things are. But the Republicans still believe in the state and they still fed the mechanism that swallows liberty. Democrats tend to express wanting liberty but they want to be libertines who are sanctioned by the state to be legally amoral.
This is an over generalization. To the original post here I see the individual Americans as great and in spite of the loyalty to party are mostly decent. It's the blindness that allows evil to flourish.
Personally, I need to be the perfect man for all of this to work and so far I'm far from perfect. Over and over again I have to realize that I'm responsible for my behavior and bad behavior is no excuse for righteous behavior.
