What a short memory you have, the Democrats spent the last four years fighting the last election results citing all manner of interference, Russian plots, dead people voting the whole gamut of swivel eyed lunacy it only calmed down a little once the 2020 election came around.That’s the rule book but it isn’t convention is it!
It’s common knowledge what the results are and despite Trump and his associates even going as far as trying to subvert the electoral college, the message is loud and clear from everybody including the Republican states that they will not ignore the democratically decided wishes of voters in each of their states.
Which means that despite the current POTUS trying every trick in the book to try and overturn a democratic vote, he’s effectively banging his head on a brick wall.
So getting back to the convention of the winner of the election being known as the president elect once the voting results point to a straightforward obvious winner. Biden has the election fairly and squarely in his pocket and Rudy and Co can run around shouting the most ridiculous conspiracy fairy tales from the rooftops but it simply isn’t working.
So yeah, Biden can legitimately call himself the president elect because that’s what the convention has always been in the past when the results are clearly indisputable.
