More than 130 million people turned out to vote Tuesday, the most ever to vote in a presidential election.
With ballots still being counted in some precincts into Wednesday morning, an estimated 64 percent of the electorate turned out, making 2008 the highest percentage turnout in generations.
In 2004, 122.3 million voted in what was then the highest recorded turnout in the contest between President Bush and Sen. John F. Kerry (D-Mass.).
Previously red states targeted by the Barack Obama campaign demonstrated remarkable turnout, setting records in North Carolina and elsewhere. Increased turnout was also reported in states including Virginia and Indiana.
Exit polls indicate that whites made up a slightly smaller percentage of the electorate than in 2004, as a surge among minority and youth voters aided Obama, who exit polls show won two-thirds of voters ages 18 to 29, 66 percent of Hispanics and 95 percent of blacks.
