Early Voters Matter? More than 2 million voters already cast ballots

Election Day is 18 days away, but could it already be over? More than two million people already cast ballots for presidential election. 32 states and Washington D.C. now allow in-person early voting and 19 are already underway and eight more start on Monday.

Early voting traditionally favors Democrats, but this year Republicans are not giving it up without a fight.  Who will benefit from this year's Early Voting?

Early voting surge suggests Democratic push pays off in Iowa

Early numbers, which are updated daily, show that almost 20% more registered Democrats than registered Republicans have voted so far.
