Bob Cesca defines the irrational end of the conservative spectrum:
Wingnuts are the entrenched crazies who routinely vote against their
own best interests. People who are oblivious to their own ignorance,
contradictions and backwards worldview. They proudly consider themselves
"dittoheads" and believe President Obama is a communist Muslim
terrorist born in Kenya and that the Constitution is a religious
document. They make up their own history and reject empirical reality.
They routinely contradict themselves and when you point out their
obvious inconsistencies, they insist that your sources are part of the
liberal media cabal.
