The U.S. presidential election is already historically unique in that an incumbent is running against another de facto incumbent, says Barbara Perry, a presidential scholar at the University of Virginia's Miller Center. Add to that the fact that former President Donald Trump is facing a combined 91 criminal charges in federal and state courts, President Joe Biden has approval rating percentages in the high 30s or low 40s, both men are showing signs of their elderly status, and the Supreme Court could end up having a definitive say in who is on the ballot, who gets to vote and who is allowed to serve – and the year gets even more dramatic. "Any one of these scenarios is unprecedented," Perry says.
