It is because of the psychological problems all leftist have. They are sociopaths to different degrees. Obama is their god because he is the most sociopathic amongst them. They all have inferiority complexes. Some because of perceived inadequacies. Some because of real inadequacies. Their main goal in life is to redirect everyone away from their own inadequacies. They are sociopaths to certain degrees, so murdering innocent babies is no problem. Destroying property during a riot is no problem. So to cover up all their problems, they project their inadequacies upon others. Mainly conservatives.
So in their screwed up minds, they see conservatives possessing all the faults they actually possess. And they can never ever acknowledge that their own inadequacies were the actual cause of the problem.
