McCain and his advisers have been arguing that the GOP nominee is gaining on Obama and is within striking distance of victory on Election Day, but Greenberg, former adviser to Bill Clinton, disputes this.
He told U.S. News that some of the battleground states such as Florida and North Carolina are close, but Obama generally holds leads that have not been eroding. Greenberg adds that Obama is now the favorite to win previous GOP strongholds including Virginia, Colorado, and New Mexico—a real blow to McCain's chances.
In fact, Greenberg argues that there in no way McCain can win the White House without Pennsylvania, which explains why the Republican nominee has been spending so much time there in recent days.
