My prediction is that the American electorate in its infinite wisdom will overwhelmingly respond to elect a Democratic Congress and, later, turn tail and elect another Republican as President.Why, you ask? Well, they have a history of doing just that.
The next Republican nominee will go so far as to distance himself from GB that you'll be hard pressed to remember they're in the same party. The conservative nominee's ultimate goal will be to say nothing and ride the middle of the road between te neocons and the religious right (who are these people anyway, and where is the massive population of people that just want to work and keep a bit of their money and be left alone, and why can't anyone harness that constituency?).
The Dems will do what they always do, nominate the most fecklessly meandering twerp imaginable. I swear to God, I have never seen a party so hell-bent on cyclical self-destruction. Mondale-geek, Dukakis-bushy-browed uber wuss, Gore-easily confused greenie wimp, Kerry-vascillating troll...
...and let's not kid ourselves, a Hillary Rodham Clinton nomination would secure a victory for the Republican Party faster than anything imaginable.

Jesus, maybe I should have learned Icelandic when I had the chance...
