According to the latest NYT poll, the Dems have lost their advantage among, well, lots of folks. The loss of the gender advantage is, I think, huge:
Republicans have wiped out the advantage held by Democrats in recent election cycles among women, Roman Catholics, less affluent Americans and independents. All of those groups broke for Mr. Obama in 2008 and for Congressional Democrats when they grabbed both chambers from the Republicans four years ago, according to exit polls.
If women choose Republicans over Democrats in House races on Tuesday, it will be the first time they have done so since exit polls began tracking the breakdown in 1982.
