What would happen if all presidential candidates died or could no longer run except for one?
That's true. Do you think that scenario has ever happened before in US History?
I'm not entirely sure. However, in 1872, the presidential nominee of the Liberal Republican Party, Horace Greeley, died shortly after the election. Although this didn't happen during the election, it did result in a unique situation where 63 electoral votes were cast for Greeley, even though he had already passed away.
