Are the Republicans Outpacing Democrats for the title of most self-destructive party?

From here

In the nine days since the 43-year-old Mr. Fossella, who has served five terms in Congress, was arrested and charged after running a red light in Alexandria, Va., things have gone from not-so-good to pretty bad, with only a slender thread still staving off the worst.
Within days of his admitting that he was on his way to visit “some friends in Virginia” when he was stopped by the police, the New York tabloids began raising questions about the woman who came to retrieve him from custody, a former Air Force lieutenant colonel named Laura Fay. Then, on Thursday, he released a clipped statement from his office, saying that he had fathered a daughter, now 3, in an extramarital affair with Ms. Fay.
The topsy-turvy transformation from young buck candidate to repentant politician is a well-blazed trail, but one that nonetheless caught his allies by surprise.

So, the current tally is two Democratic governors in NJ & NY upset by scandals versus at least 5 Republicans involved in DUI, prostitution, soliciting in restrooms, and who knows what else.

I'd put it down to some vast left-wing conspiracy, but unless Harry Reid was buying him his drinks and suggested he drive to visit his illegitimate daughter, I'd find that a hard sell.

So are Republicans more self destructive or are news organizations downplaying similar stunts by Democrats due to partisanship or because this behavior is more expected from Democrats and hence not newsworthy? Or is this just hubris brought on by power?
