An election for President in the United States is not a national event. It is a collection of 51 separate elections. There is no way Romney is going to carry New York or California, and there is no way Obama is going to carry Texas or Mississippi. So the campaigns will focus on winning the swing states. Here they are: Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin. Whichever candidate wins more of these states will win the election.
