Experts have long considered New Hampshire a vulnerable state for incumbent Obama. The president won there in 2008 by nearly 10 percentage points, but Romney's New England connection has kept him competitive.
The final polls show Obama ahead of Romney 49.9% to 47.9%, or 2 percentage points, but Romney held a slight aggregate poll advantage for a couple days in mid-October.
Though the state's four electoral votes don't seem great, they are another four votes that if Romney can somehow squeeze out a win would suggest election day momentum in favor of the challenger.
