Successful psychopaths
Successful psychopaths are attracted to the republican party for the same reason pedophiles are attracted to the catholic priesthood; it gives them cover.
There are at least a hundred right wing think tanks out there fine-tuning carefully crafted lies phrased in the language of high sounding principles whose aim is to harden and increase the biases of average American in such a way as to get them to vote for candidates that will enforce a vicious status quo.
They play to the strength of hatred and intolerance and hide it in the language of high-sounding principles.
Their strength is based on carefully managed bigotry, sold to them as a virtue.
They feel good about themselves and smarter when given an ideology that tells them that their bigotry is a virtue.
They sell a return to a golden age of the 50s, that is, a pre-civil rights America. To bring this about, right wing radio shows have for decades stoked the fires of bigotry. Is it any wonder that folks who listen to their message eventually act on it?
Realizing that they have jumped the shark, they are pulling back and trying to regain credibility for their core ideology. But there in lies the problem; their core ideology is the fountain head of all things foul that they have fostered on the American public.
