29 states and the District of Columbia had Democratic party affiliation advantages of 10 points or greater last year. This includes all of the states in the Northeast, and all but Indiana in the Great Lakes region. There are even several Southern states in this grouping, including Arkansas, North Carolina, and Kentucky.
An additional six states had Democratic advantages ranging between 5 and 9 points.
In contrast, only five states had solid or leaning Republican orientations in 2008, with Utah, Wyoming, Idaho, and Alaska in the former group, and Nebraska in the latter.
