Wish that were true but I'm afraid it's not. While I don't necessarily buy into the conventional wisdom of the "experts" that seem to be in the spotlight 24 x7 that the Republicans are doomed and will be swept out of power in both the House and Senate, that there is a possibility of it happening would indicate they're not dead yet.
The Dems believe they can take the House and Senate. I do not believe they can or will...the Dems are famous for believing their own (in this case early) polling data. They believe if they can demonize GWB sufficiently, they will win. They won't.
