Even Jim has asked here, "Will you accept the results?" Several Dems are saying trump won't leave office. They are setting the table to once again challenge a Trump win, and then claim he just won't leave office, and the military has to decide who is president (drag him out or not).
With mail in ballots, as we have seen in New York, we won't know some states votes for a couple months.
If states go to mail-in ballots, they better pass a provision that allows the Electors of the state to be decided by the state legislature. Mail in ballots will trickle in for weeks, and can be sent by anyone, and the Dems will insist on counting them no matter what, even if invalid...(to challenge the win by Trump. I wouldn't be surprised to see competing state certifications of Electors Multiple from the same state), with the House having to decide which sets of Electors to accept. If we are lucky, it will be lawsuits galore. If we aren't lucky, violence will ensue.
The dems will not accept the results of the election if trump wins.
