Yes, the problem with a brokered convention is that you alienate people either way.
That’s why I like the 1st, 2nd, 3rd choice option for primaries.
If 60% of the people love citrus fruit, but hate aplles, one apple can easily win a plurality, if an orange, a frapefruit, and a lemon are in the race.
I like the 1st, 2nd and 3rd choice voting too. But it could still result in a result sheet that shows somebody was #1 based on the first choice vote, but the actual winner was selected based on the second choice vote. People would have trouble understanding that and Trump would almost certainly raise a ruckus and obfuscate the process to make his supporters think it were stolen from him if he was the first choice winner.
