What is it about holier-than-thou public officials and seedy crimes and misdemeanors? Why do Re publicans have their own special brand of scandal and Democrats their own?

It seems that Democrats are always the ones tripped up by infidelity. Or maybe, in the old days, they got away with it, and their well-known penchant for playing around merely added to their appeal. We are thinking now of JFK, of course.

Later on, Sen. Gary Hart tried the same sort of thing, but the press was no longer compliant, and he sunk out of sight as a viable presidential candidate. Monkey business would no longer be tolerated.

Bill Clinton, incredibly, seemed to believe he could return to the Kennedy era, when everyone gave a wink and a nod but said nothing, but he wound up on Impeachment Row.

Republicans, probably because they are prone to moralizing and proclaiming their religious convictions to get elected, often seem to have repressed urges that become public knowledge because, at some point, they just couldn't help giving into them at an inopportune moment. They are closest to those infamous evangelists, like Jim Bakker and Jimmy Swaggart, many of whom, coincidentally, are conservative GOP supporters.

Idaho Sen. Larry Craig appears to

be the latest victim of his own weaknesses, and suddenly is an embarrassment to the party, which is taking steps to push him off a political cliff.

Why do men in power - so far, few women seem to have these tendencies (or they are too clever to get caught) - keep pushing their luck until they wind up in mug shots and apologizing on "Larry King Live"? It really is a mystery.

As the undercover police officer who arrested Sen. Craig said to the senator at one point after the incident, "I expect this from the guy we get out of the 'hood. I mean, people vote for you. Unbelievable."

Exactly.
