What matters in these affairs is election certification by the respective Secretaries of State, not whether the losing candidates concede or the winning candidates claim victory.
Still, it is considered un-American not to concede when you've lost, simply because that means you don't accept the rules Americans agree to live by in these matters. Without that glue, the whole thing is in danger of descending into chaos, conflict and perhaps civil war.
One such un-American person stoking these flames is Democrat Senator Sherrod Brown of Ohio who said "if Stacey Abrams doesn't win in Georgia, they stole it, it's clear. It's clear. I say that publicly."
Obviously not clear to the final authority in this matter, Senator.
In rejecting the non-conceders, one might say the voters got it right in electing their opponents, including in Alabama, except that in Ohio Sherrod Brown just won six more years in the US Senate by 275,000 votes.
The mills of the gods grind slowly . . ..
Gillum had conceded to DeSantis on election night, but retracted it after the margin between the two candidates narrowed.
Her speech Friday effectively puts a stop to the contest. The final result had been in doubt for 10 days after the election.
Abrams stressed as she spoke: "This is not a speech of concession."
