Anon, it should be clear that the democrats are going for broke at the moment.
They are going to outright declare that President Trump is trying to steal the election or otherwise refuse to leave the whitehouse. They are going to call on civilian and military sympathizers to take armed action and assault the President and his administration.
In either event, it is literally impossible to hold an election. There are mail-in ballots being mailed out ad we speak and there will be regions counting those as valid votes while entire states refuse to accept the results of states/regions which do mail-in voting.
It will come to war in either case. They may wait for the election to be held - but the results are immaterial.
