Remember 2006?

TechRepublican today makes a good point, referring to some data on the 2006 midterm elections that leaked recently from Karl Rove's office: the 2006 election really wasn't a blowout. Many of the races were very close, decided by a few thousand votes or less. That doesn't mean that Republicans need not worry about 2008. It doesn't mean that Democrats are in trouble in 2008, necessarily. It does mean that for the GOP 2008 remains doable.
