Noam Chomsky said this quote

Since Jimmy Carter, religious fundamentalists play a major role in elections. He was the first president who made a point of exhibiting himself as a born again Christian. That sparked a little light in the minds of political campaign managers: Pretend to be a religious fanatic and you can pick up a third of the vote right away. Nobody asked whether Lyndon Johnson went to church every day. Bill Clinton is probably about as religious as I am, meaning zero, but his managers made a point of making sure that every Sunday morning he was in the Baptist church singing hymns.
