If the race is very close in certain states then he'll ask for a recount, i.e..like Gore did in Florida which I'd understand. I would expect Biden to do the same.
I think he will leave but I do not think he will admit defeat because, well, when has he ever?Yes he will leave, any president knows it would be senseless to do anything but quietly leave.
Anyone saying otherwise is just trying to get people worked up over nothing.
I remember a bunch of right wingers getting all bent out of shape about Obama not leaving.
It was silly then and its silly now.
I think the scenario people are scared of is that somehow due to corruption and confusion, we will end up with 2 sets of numbers from the polls, one showing trump as winner and one showing Biden. Or say initial numbers say Biden but then trump demands a recount in certain states due to mail in votes or stating that certain districts are invalid for whatever reason and they switch to trump. And then Biden challenges that in response etc,,Lets say a president locked himself in the the Oval office and ranted I'm still president on swearing in day.
A new president would be sworn in and he would just be a powerless laughing stock throwing a tantrum in the oval office.
The newly sworn in president would have the presidential power.
A week ago I’d have thought it extremely unlikely that the US President would order peaceful protesters to be tear gassed in order to do a photo op at a church he hadn’t been invited to.The founders saw that disputed elections might happen which is one reason for the electoral college. Its vote is the final say.
My point is there are enough real issues to worry about wihout making people worry about something that is very extremely unlikely.
