NBC just called Ohio for Obama. By their projections, Obama needs 75 more votes to clinch. California, Oregon, Washington and Hawaii would do it for him. Virginia, Florida, North Carolina, Nevada, Colorado, New Mexico, and Indiana could all be made irrelevant. As I've typed this, I just saw ABC, CBS and Fox have also called Ohio for Obama.

Addendum made a minute later: those 4 states would clinch for Obama under projections by NBC, ABC and CBS right now.
