Senates with elections

Note: The figures in Column 3 ("Seats up for election") include a handful of seats that were up for election on November 2 in districts where a state senate election would not normally take place this November but where a special election is occurring to fill a vacancy in a seat where the seat would normally not be up for election until November 2012.

The figures in Column 5 ("Seats impacted by term limits") only reflects current members of state senates who are unable to run for re-election to their state's senate in 2010 because of term limits. In some cases, including cases in Arizona, Colorado and Nevada, state senators who would have been unable to run for re-election in November resigned earlier in the year. Senators who resigned, and are not current members of their state senates, are not counted in these figures.
