Here's my best guess:
Popular VoteClinton/Warner 52.8%
Romney/Ridge 45.7%
Other 1.5%
Electoral VoteClinton/Warner 360
Romney/Ridge 178
Overall, the election is not that much different than what takes place in real life. However, instead of competing in Indiana, Clinton competes in both Arkansas and West Virginia and she wins them both. She of course loses Indiana. Clinton competes in North Carolina, but narrowly loses there, but she narrowly wins in Missouri. Additionally, unlike Obama in real life, her campaign makes no attempt to organize in Omaha, and Romney takes that electoral vote. Finally, Michigan would have been Romney's last stand instead of Pennsylvania (which was McCain's last stand in real life), but Romney would have still lost there by 10 or 11 points.
