A drop in voter turnout didn't keep President Barack Obama from winning a second term in the White House.

Early figures from states where more than 90 percent of the vote has been counted suggest fewer people voted this year than four years ago, when voters shattered turnout records as they elected Obama. That from Curtis Gans, a voting expert from American University.

In some states, turnout appears to be substantially lower than in 2008. And in most states, the numbers are shaping up to be even lower than in 2004.

The full picture won't be known for weeks. That's because so many Americans this year voted early or by mail, especially in states like California.
