When will honest Republicans With access to the president or any adult who might still be in the White House or near the president tell him that this is over? His selfish petulance is actually hurting the nation.
1. Al Gore didn't concede until more than 30 days after what used to be known as "Election Day".
2. "Conceding" is not in the Constitution.
3. "Conceding" does not end the lawful count of ballots, their certification by each State, or the action of the Electoral College.
4. If Joe Biden won, it doesn't matter if Don Trump concedes or not.
5. What is the history of transition cooperation? Trump didn't get much of it in 2016-17 from the outgoing Administration, and it showed. In my opinion, absolute cooperation and transparency is essential, except that I don't think it is either wise or lawful to share the nuclear codes, provide open access to ongoing negotiations for hostage releases, to open the book on active military operations, to pick rather globally relevant examples, until we officially have a new President installed.
Other than that, do you personally know any honest Republicans or adults in the White House?
If you do, perhaps a worthwhile thing to do for the sake of not hurting the nation is to encourage them to act responsibly to carry out the law of the land including acts of civil mercy for the hurting.
