The polls on the east coast close @ 6 p.m MDT. By 5:30 MDT the media will declare Hillary the winner. That includes saying places where the polls still have 1-3 hours before they officially close, ballots are already counted.
The did it in 2012 when CA still had 30-45 min before closing, CA was called for Obama. It happened with Bush v Gore (iirc) calling FL when 1/3 votes were not counted since Fl sits in 2 time zones
I hope my prediction is wrong.
