There won't be a concession speech. By November 7th, President Trump will have negotiated the terms of the election such that 2016 will be the first year without need for an election day. He'll simply buy out Pence's losses and run on a Trump-Trump ticket.
By late October it will have become obvious to Donald that the only thorn in his side was other people, all along. When America hears that he plans to run for both president and vice president, that will serve as the final battle cry behind which all men shall rally; Men who will tell their women, "Donald! Donald!". $hillary will falter almost immediately. After November 6th, the majority of America will have already voted unanimously for Trump, so all citizens need not leave their workstations on November 8th.
