Some of these states do not begin to count early votes until after polling stations close, and some allow ballots that arrive after Election Day to be included as long as they are postmarked by Nov 3. If the presidential race depends on the outcomes in these states, America could be waiting for days.

Experts have cautioned against reading too much into early returns, which could be distorted by how each state processes the votes not cast in-person on Election Day.
