When Donald Trump lost to Joe Biden in 2020, it seemed to be the death knell of his political career.
His first term in office ended in chaos and condemnation - even from members of his own party.
If he wins the election on Tuesday, it will be only the second time anyone has ever returned to the White House after previously losing a presidential re-election bid. "He gets knocked down and gets up twice as focused," said Bryan Lanza, who has been a political adviser for the former president since Trump launched his 2016 campaign. "I don't think anybody should be surprised about this comeback." Such an extraordinary reversal of fortune for the 78-year-old former president would also vault him back into the White House as a man who seems politically bulletproof, with a detailed plan of action and ranks of loyalists behind him.
Four years ago, Trump appeared a beaten man.
