The trend here is that suburban and independent voters moved into the GOP column. The overall shift away from Democrats was 13 points in Virginia, 12 points in New Jersey, and eight points in Pennsylvania.

Even a five-point swing in 2010 could bring a tidal wave of change. Today, Democrats enjoy 60 votes in the Senate, Republicans a mere 40. Had there been a five-point swing away from Democrats last fall, the party would have started this year with 54 seats and the Republicans 46…

Looking ahead, the bad news for Democrats is that the legislation that helped lead to the collapse of support for their party on Tuesday could yet inflict more pain on those foolish enough to support it. The health-care bill House Speaker Nancy Pelosi wants to vote on this week could sink an entire fleet of Democratic boats in 2010.
