With Trump, it’s pretty clear what he ought to do - he should concede once it’s shown that Biden has hit 270 and the mail in ballots are only going to expand that lead. (Trump won’t actually do that, of course, but it’s what he ought.)
But with Biden, it’s a different story. Hillary has already urged Biden to never concede. Trump may surge into the lead based off of in person voting but the mail in voting will Iean heavily blue. Trump may then mount challenges in court and it could go all the way to SCOTUS.
If the Supreme Court rules, for instance, that it’s ok to toss out many legit Biden ballots and Trump wins as a result, should Biden concede?
What if it goes to the House and Trump wins 26 delegations to 24?
Isn’t conceding almost meaningless? It indicates that the candidate doesn’t plan to file legal challenges. But if a candidate concedes and the final vote is in their favor, don’t they still win? Each state will still send the appropriate electors, etc.
I tend to agree. I don’t think it has any technical significance. I always saw it more as a symbolic way to indicate to the nation an acceptance that the fight is over, and we should now unite behind our new president. Under the current circumstances, that notion seems kind of ridiculous.
