Political insiders are buzzing about the departures of Oregon Congressman David Wu's staff. Six members have recently quit, including his Chief of Staff and his top pollster. Oregonian political reporter Jeff Mapes says there are no clear answers. Mapes says there is typically turnover in Congressional offices, but it's uncommon to see so many departures. And the people involved aren’t talking. But Wu recently went through a hard fought political campaign and is going through a divorce.
