Exit polls suggest bad night for Dems

It's pretty much everything they had been fearing for weeks. From WSJ:

In 2006, when Democrats took control of the House, the party held a 12-point advantage among women, exit polls that year showed. That lead now appears to have been all but erased. The shift appears to be even larger among white women. The parties were evenly divided four years ago among white women, but on Tuesday a decisive majority of that group went for the GOP. Among seniors, the two parties were at parity in 2006; Republicans now hold a large advantage among voters age 65 and older. Equally damaging for the Democrats, seniors--who were heavily courted by Republicans this year with ads attacking Mr. Obama's health-care overhaul--appear to represent a larger share of the electorate than four years ago.
