According to an article in the Washington Post, only 18 states are in the running this year for the race to the White House. The other 32 states are essentially locked in by one side or the other, and won't affect the outcome of the election at all. As a result, both the Bush and Kerry campaigns will focus all their hundreds of millions of dollars in campaign war chests on these critical states.
The states include: Florida, West Virginia, New Mexico, Arizona, Oregon, New Hampshire, Missouri, Ohio, Pennsylvania, Nevada, Minnesota, Iowa, Wisconsin, Maine, Arkansas, and Louisiana.
