Whoa. Larry Sabato, University of Virginia professor and human quote machine, writing at Rasmussen:

The Crystal Ball projects that the Democratic majority in the Senate would be reduced to just 52 seats if November’s contests were somehow moved to January.

That would be a pickup of an additional seven seats. What’s more, Sabato’s list of the newly vulnerable is jaw-dropping:

Among the senators who could be endangered by a new wave of Republican entries are Evan Bayh (Indiana), Kirsten Gillibrand (New York), Patty Murray (Washington), and Russ Feingold (Wisconsin).

And this is with only three months of 10 percent unemployment. What happens if we’re at this level for a while, and the unemployment rate is still at, say, 9 percent in November?
