It's official -- Rahm Emanuel will sign on as Obama's Chief of Staff (potentially a great move for Obama, in my opinion). While the timeline is unclear, Rahm will soon be stepping down from his seat in the House, triggering a special election. Rahm's district has a PVI of D+18, so there's no reason why we can't fill this seat with a solid progressive.
This leads me to ask -- where else might we see retirement (or resignation) announcements before the next election? Roy Blunt is stepping down as the House Minority Whip, and you have to wonder whether he'll ride off into the sunset and quit politics altogether. And there are plenty of crusty GOP oldsters like Roscoe Bartlett (MD-06), Bill Young (FL-10), and Ralph Hall (TX-04) who may call it a day. And on the Dem side, Leonard Boswell will always be the subject of retirement rumors.
It's never too early to start thinking ahead to the next round of elections. Which House seats do you think might open up in the next two years?
