How about you flip this theory on the head? Any dem could've won '92 due to Perot splitting the vote by running third party, meanwhile, no other rep could've won '16 due to Trump splitting the vote by running third party had he lost the primary, he said from day 1 and even before entering the race that he would run independent if he lost the primary. He could put Trump Jr's name on the ballot in states with loser laws and he wouldn't need that much money to spend (just ~100 mil), Perot didn't spend that much either (he spent ~100 mil inflation adjusted), Perot mostly got Free Media.
How's this for an interesting option?
