REMEMBER ... 87% of the electorate is public school HS graduates and (I'm guessing) about 20% of those are liberal arts (commie) college degree holders.
Bottom line, about 60% are card carrying socialists and have no clue what the Constitution says and would actively erase it from our history.
(Some already making that attempt)
Concessions are not binding. They are words. Remember Al Gore?
I do not think concession has any legal impact. It is a public relations issue, not legal.
