Democrats tighten grip on House, Senate

House and Senate Democrats strengthened their hold on Congress Tuesday, soundly defeating GOP incumbents including Sens. Elizabeth Dole and John Sununu and Reps. Tom Feeney and Robin Hayes in a widespread repudiation of the Republican brand.

House Democrats were expected to add about 25 seats to their 17-seat majority, while the Senate Democrats were predicted to increase their one-seat majority by about seven seats, leaving them just one or two shy of a filibuster-proof, 60-seat majority.
