Eight to ten states will be electing the President if current trends continue.
Forty states plus DC produce a 221-191 edge for President Obama. In a close national race, those states are a lock.
Ten so called swing states are mostly leaning to Mr. Obama and if that holds the Electoral College margin is to 332 to 206. Mr. Romney has to win Florida, Virginia, Ohio, NC and one other state like an Iowa to win. Currently only NC is in his column.
