Random Thought Prediction
2008 Tickets: Hillary/Bill Richardson vs. Giuliani/Jeb Bush? (Too early for Obama?)
2012: If Hillary wins, a Northeast + Southwest coalition becomes the heart of the Dem. Party, so 4 years later, it's Hillary/Richardson vs. Arnold/Pataki (plus a 3rd party cultural conservative nut-job representing the Republican Party split over social issues). If Giuliani wins in '08, it's Obama/Bredesen (the ignore-the-south strategy finally repudiated)vs. Giuliani/Bush
