At least 30 million people already have voted in 34 states and the District of Columbia in this year's presidential election, either by mail or in person.
But no votes will be counted until Tuesday. Some key states have released the party affiliation of early voters.
In Ohio, 1.6 million people have voted -- 29 percent of them Democrat and 23 percent Republican.
And at least 4.3 million people have cast their votes in Florida, with 43 percent being Democrat and 40 percent Republican.
