Whenever a congressional sex scandal breaks, members of the opposing party revel in the details of the implicated official’s misdeeds: Though the story of Representative David Wu’s unsavory sexual encounter with a teenage girl might have gotten more press had it come to light while Washington wasn’t focused on the debt-ceiling crisis, there was at least a cackle or two from the Republican side of the aisle as the details leaked out. After all, this was the second scandal in a row — following Anthony Weiner — that forced a Democrat to resign. For the moment, at least, lefties appeared to have a leg up in the dubious whose-elected-officials-are-pervier competition. But in 2010 and 2011 to date, an equal number of Democrats (Wu, Weiner, and Eric Massa) and Republicans (Christopher Lee, John Ensign, and Mark Souder) have been involved in prominent sex scandals. So it’s a perfect opportunity to take a dispassionate look at whose passions have been more embarrassing for their political parties. Below, a scorecard. Not all these details are precise moral equivalents, but they got roughly equivalent airing in the press, so we’re treating them as such for the purposes of an (appropriately?) quick-and-dirty comparison.
