"Let me put it this way.
Conservatives believe in God. Liberals believe in Santa Claus."
That would be said correctly like this...
Conservatives believe in their own self-serving vision of God and use it to pass judgement on others. Liberals believe in the freedom of religion that our nation was founded on.
On a side note, who cares who believes in God, at least for us Americans, God is a non-issue in a political forum. Well unless you want be unconstitutional.
