Assuming he looks in the mirror, Cong. Bob Etheridge will not like the answer. Althouse has the video.
Let's set aside partisanship for a moment. The problem here isn't what side of the aisle this dude sits on. The problem is that he seems to think, assuming he was thinking at all in this incident, that he's entitled to live by a different standard of behavior than other people. We always need to keep in mind the difference between a governing class and a ruling class. It's this sort of behavior that leads to Tea Party movements.
If you choose to be part of the governing class, you can reasonably expect scrutiny, whether it's from dudes in blue blazers with flip camera, or from Code Pink or SEIU or any number of other people. It's a blood sport and given the enormous amounts of money and power involved, that shouldn't surprise anyone. But the minute one of our representatives, regardless of party affiliation, begins to act as though they are part of a ruling class, they need to go away.
