The Democrats have given up the Southeast consistently since the Clinton years are over. Gore not being able to win Arkansas and Tennessee was a big indicator of that, but I think it was partially a strategic flaw and not that he COULDN'T win those states.
And only this year might they break back into the Southwest again.
The Perot factor is one reason the democrats did not lose the South sooner, though.
A Democrat can't win in the South without Dixiecrat votes.
It's a tiny thing, but I'm interested to see if McCain is actually popular enough in New Hampshire to win back that state like Bush did in 2000. It probably won't decide the election, though.
I think the turning of Iowa back to blue is a really big deal, and I think it's B.S. to call Michigan a swing state just because of Reagan Democrats in metro Detroit. Michigan is a mess right now, and the state is being flooded with "We Just Can't Afford More of the Same" ads.
And they're working.
