A view from the Daily Kos which scrambles the data from 2004, weights it and finds that Hillary could get mashed in November, while Obama becomes the biggest Democrat winner since 1964
OK, my first impression is it overstates the Democratic party's position, by perhaps overcompensating some effects (I'll have a closer look before elaborating).
But here's the bottom line:
Barack Obama: 289 electoral college votes (and wins the popular vote by 0.9%)
John McCain: 249 ECVs
With 5,000 re-runs Obama wins 64.2% of the time, allowing for variations in the margins of error to play, for example.
Hillary Clinton: 239 electoral college votes (and loses the popular vote by 1.4%)
John McCain: 299 ECVs
With 5,000 re-runs Clinton wins 37.6% of the time.
Incidentally, if the latest crazy Democratic plan to demolish the Electoral College were applied, California's EC votes to go to the winner of the national popular vote, regardless of who wins in California, Hillary Clinton would win California in terms of votes cast, but get nothing there in terms of EC.
So the total would be:
Previous attempts to lose the election next time by changing the rules to suit the last election include the very dubious 2004 Colorado proposal which would have changed the system at the same time as people voted (so they wouldn't know when they voted how these would be counted).
