La previsione di Larry Sabato

If Barack Obama wins the popular vote by 7 or 8 percentage points, then he will also carry at least a couple of the following states: Arizona, Georgia, Indiana, Montana, North Dakota.

If Barack Obama should end up by 3 or 4 percent of the popular vote, then it is possible that John McCain will carry a couple of the following states: Florida, Missouri, North Carolina, Ohio.

The Crystal Ball expects Barack Obama to run closer to the maximum than to the minimum in the popular vote tally.
