Unfortunately I have some bad news - the election will most likely go on for weeks after election day. In GOP controlled states - the GOP will lie and say there are "discrepancies". No proof, data or facts will be provided but eventually at least one case will go to the supreme court. And - of course - Trump wins on that day but a façade of democracy and legal procedures plus paperwork is needed so there'll be another couple weeks were the supreme court pretends to debate the issue.

The "deadline" is January 6th. My hunch is that election ends mid-December.
