Guys who smile in Mugshots: Republicans or the Mafia?

Are guys who smile in mug shots more likely to be Republicans or in the Mafia? It’s a great question– one that we’ll be trying to answer here repeatedly in the coming months as we start to see more and more mugshots of Republicans.
Tom Delay looks pretty peachy in this picture. He had reason for that, of course. He’s innocent!

No, seriously, though, folks… Tommy “The Hammer” was smart enough to realize that mugshot in which he looked terrible would get a million times more press than this smiley-faced gem. Imagine the classic mugshot: Unshaven, pinstripes, haven’t-had-coffe-yet look on the face, occasionally shirtless, hair all over the place– that’s a picture that would’ve have legs.
It looks like Gotti was smart enough to realize the same. Unless of course it’s just a matter of vanity, which I’m not ruling out. Although, if Delay was the vanity-type, we would think he’d have done something about that hair.
