WASHINGTON – Democrats are expected to pick up two more Republican Senate seats: North Carolina and New Hampshire, according to projections by television networks.

After a campaign that turned particularly nasty in the final weeks in North Carolina, Fox News projected Democratic state lawmaker Kay Hagan would defeat incumbent Republican Sen. Elizabeth Dole.

Meanwhile in New Hampshire, NBC News projected that Republican Sen. John Sununu would lose to Democratic rival Jeanne Shaheen.

Together with the earlier projection that Democrat Mark Warner would capture Virginia’s Senate seat being vacated by retiring Republican Sen. John Warner, Democrats would pick up three seats so far based on the projections, expanding their lead to 54-46.

Republicans were able to hold on to another seat that was considered potentially vulnerable early in the campaign season, Maine Sen. Susan Collins.
