Mitt Romney's behavior is very similar to that of Idaho Senator Larry Craig. Craig had a virtually 100% anti-gay record in the Senate, consistently voting against gay marriage, civil unions, and hate crime penalties for crimes against homosexuals. Other behavior of Senator Craig included "lewd conduct" in the men's room of Minneapolis-St. Paul International Airport.
Psychologist say this extreme contradictory behavior is indicative of what some people go through to hide their real self from a hostile society.
Mitt's anti-gay zeal is obviously hiding something. He hasn't yet been caught with his pants down, but since he is apparently demonstrating his fellatio technique (above), it's just a matter of time.
