I think it's assumed that if a politician or religious leader is saying something, it has no foundation, and is being used to deliver votes or dollars from the uneducated.

I don't think anyone actually 100% believes anything a politician says, even a politician of the party they agree most with (usually agreeing with things they don't agree with just to get agreement for the things they do believe in).

Fact is... politicians are scum. Most of them are lawyers.
