This map shows Obama potentially up 281-235, with 22 votes in the toss-up category.
Throughout the night, as state are called, I'll be coloring states darker on the map. Also, I'll give numbers this way:
Obama: 0 Confirmed, 237 likely, 44 probable, 281 total
Romney: 0 Confirmed, 180 likely, 55 possible, 235 total
Confirmed is states that they have won, likely is the darker-blue numbers, possible is the light blue.
