One note: The "O/K" column refers to the share of the vote that Obama and Kerry respectively got in the district. In any event, the vagaries of redistricting obviously make selecting endangered incumbents a difficult enterprise, but there are still some notable names missing on this list. Who else do you think should be on here?
