The second possibility, that Donald Trump refuses to concede the election and does not freely leave the White House, has stirred anxiety among some people, but may be far-fetched.
The president is unabashedly concerned with image, and being forcibly removed from office would be a bad look, to say the least.
“That it gets to a point where he is escorted out of the White House […] is something he probably wouldn’t want,” said Mr Birdsong.
Despite this, large numbers of Republican lawmakers are yet to turn away from Trump’s baseless allegations of foul play - or at least do so publicly.
While these officials would be unlikely to champion an attempted coup (the president refusing to give up power), it’s difficult to pinpoint where their support will end, as many still fear some form of political retribution.
This leaves the final scenario, which is the first Google suggestion to appear if a user types in “can Donald Trump”: the president, through various legal avenues, overturns the result and lays claim to four more years.
“That one makes my head hurt a little bit to think about,” said Mr Birdsong. “There's one theory out there that perhaps by blocking the certification of votes in some of the states, that it would then not be decided in the electoral college, but then go to the House of Representatives.”
Despite Democrats holding the majority in the House, the selection of the president is not an ordinary vote, but one that comes down to state delegation.
“And so, if you have a state that has more Republicans than Democrats in the House delegation, then even if that state voted for Biden, you could flip it to Trump,” Mr Birdsong said.
