For voters in more than the usual number of states, this is one election where you may need a scorecard because of the wealth of open seats.
A dozen Senate seats are up for grabs because the incumbent either retired or was defeated at the primary level. In the House, there's almost four dozen such seats.
Here's a snapshot of the candidates and the current seat holder, who's not on the ballot this year.
Current: Lisa Murkowski—Republican (defeated)
Current: Chris Dodd—Democrat (retiring)
Thirty-seven imcumbents are retiring (several to compete for open Senate seats or governor posts). Twenty are Republicans; 17 Democrats. Four incumbents were defeated in primaries. Five vacancies will be filled by special elections before November.
A couple contests, however, stand out, because of the incumbent's long length of service and prominent committee posts.
