The 2006 election left a lot of unfinished business: a number of Republicans in Dem-friendly districts who survived strong challenges and got a two-year grace period. The 2008 saw another swath cut through these folks, but there are still some left to be picked off, so this list should give us an idea of where to train our fire in 2010 (and also where to expect retirements). Here are the top 10 most Democratic-leaning districts, rated by current PVI (note that PVIs will change soon, once clearer presidential numbers by district are released) represented by Republicans, before and after this week.

Note that we're down to only 9 GOPers left in districts with Dem-leaning PVIs (with the departures of Porter, Fosella, and Knollenberg as well).
Now let's look at the flipside: Democrats in the darkest red districts. Not as much turnover here, but obviously it suggests Walt Minnick will be our greatest vulnerability for 2010 when he runs against a non-brain-damaged opponent.

Nancy Boyda was #13 on the old list, and Don Cazayoux was #19. Kratovil and Markey will slot in on the new list at #11 and #13. Also, note that we now hold the 14th (ID-01) and 19th (TX-17) most Republican-leaning districts in the nation. The flipside of that, if you can imagine, would be if the Republicans held IL-02 (Jesse Jackson Jr. at D+34.9) and MA-08 (Capuano at D+33.0).
