Looking at France panicking because 2 weeks after snap election there isn’t a clear majority, nor a coalition ready to propose a prime-minister to the president. What would be the standard time to do these negotiations in a functional democracy where doing coalition is common but doesn’t take years (so US and Belgium do not coun :) )

Technically, the Electrical College could not elect a candidate, which would lead to multiple ballots within Congress until a decision is made. However, that only happened once and the Constitution was amended to reduce the odds this would happen.
