In a 33-state contest, even though there were four serious contenders from four separate parties (Republican, Southern Democrat, Constitutional Union and Democratic parties)....ONLY three walked away with Electoral College votes in November of 1860.
Lincoln took 18 states and 150 EC votes to win. Breckenridge of the Southern Democratic Party took 11 states and 72 EC votes for second. Bell took 1 state (Missouri) for the Constitutional Union Party....giving him only 3 EC votes. And Douglas won ZERO states....zero EC votes.
What you tend to find in the state by state voting....there were two significant people on the ballot that split the state voting, and if there were one or two additional people on the ballot....they never (combined) took more than 20-percent of the state by state ballot votes.
So if you were discussing a Trump, DeSantis, Newsom and RFK Jr election....it would likely run the same way.
I would suggest that RFK Jr would walk away with zero EC votes in the end, while taking around 15-percent of the national vote. DeSantis? Same way....he might get two states by the EC vote, and get less than 10-percent of the national vote. Newsom is harmed by the RFK vote, and likely only gets 20 states by the EC count.
