This most incomplete history lesson omits the most important fact:
NEVER, since the early 1850s when the party was formed, has a candidate gone into the convention with 90% or more of the required majority and been denied the nomination. In fact, I have looked at every “contested” convention and the most a candidate ever had and didn’t become the nominee was 80% of the majority number, I believe.
Trump will easily attain the 90% number, and may well attain 1237 before the convention, but however you cut it, depriving him of the nomination given the numbers he will most certainly attain would be literally unprecedented.
Thanks for the data. I would say that there is a first time for everything.
