Election 2010: Congress (Updated)

The Cook Political report has elevated to toss-up its rating for the seat held by U.S. Rep. Alan Mollohan, D-1st.

"These are the most competitive; either party has a good chance of winning," the analysis explains.

Rep. Nick Rahall, D-3rd, meanwhile finds his race entering Cook's rankings for the first time, as "likely Democratic."

Such seats, "are not considered competitive at this point but have the potential to become engaged," the report notes.

Cook has repeatedly upgraded its competitiveness rating for Mollohan's seat in recent weeks.

The seat of Rep. Shelley Moore Capito, R-2nd, remains unranked.

The ratings from The Rothenberg Political Report, Congressional Quarterly's CQ Politics and The National Journal's The Hotline appear unchanged.

Update: Larry Sabato's Crystal Ball has added Mollohan's seat to its rankings, as "Likely D."
