No, it's the number that makes a majority vote.
"It should be the one with the most votes."
Absolutely not. Without a majority the one with the most votes is just the one with the largest minority. Minority does not rule, for good reason.
An election is supposed to be about ideas and policies, not just personalities. In a multi-candidate election you can have multiple candidates with similar politics, and they are going to split their voters between them.
If it were just the largest number then someone representing ideas accepted by a minority of the party could win the nomination. As it is, the delegates can agree to settle on a candidate who represents the views of the party and combine their vote, and not hand it to a minority.
That's why in this scenario, a political party's nomination, it's not only acceptable to run it this way, it's necessary.
“As it is, the delegates can agree to settle on a candidate who represents the views of the party and combine their vote, and not hand it to a minority.”
When no candidate gets 1237, the nomination will go to what you call a minority anyway.
In your scenario, the party picks the candidate. That’s exactly what the GOPe wants to do, bypass the will of the people. Ironic that them doing this for decades is why most GOP voters prefer Trump.
