Right-wing wackjobs don't have Christian values. These people worship fear. It's the only emotion they understand, as it is the emotion they feel most. Everyone is a threat to them. Bush plays on this fear, and uses them to push his agenda. Fear breeds mistrust. They won't hold together unless they can be made to fear even more. Here in America there is a limit to just how much fear you can push on people.
Obama Tearfully Thanks Volunteers.
And I couldn't say it better.
