Preliminary statistics released Wednesday from the ongoing early voting of U.S. presidential election showed that Democrats outnumbered Republicans in key states.
With the Election Day less than a week away, registered Democrats in North Carolina are outvoting Republicans by a nearly 2-to-1 margin, state officials told the CNN.
The turnout of Democrats also appears to be higher in five other battleground states, including Colorado, Nevada, Iowa, New Mexico and Florida.
The numbers suggest that this election is shattering the traditional early voting patterns in which usually more Republicans than Democrats turn out.
Some estimates said about 15 million early voters across the country have cast their ballots as of Wednesday.
U.S. Democratic presidential nominee Barack Obama is taking a 53 to 34 percent lead over his Republican rival John McCain among early voters, according to a poll released by the Pew Research Centre Tuesday.
