Great point. You can count on that happening from here on out if the leader isn't "chosen" by the establishment, they will simply nullify the voters.
The establishment is fomenting hatred against the front-runner in order to preserve the status quo.
Next election cycle it will be your guy getting blitz-kreiged.
My point was that the idea of gaining a majority being the way a nominee is chosen leads towards an eventual coalescing of support. The party comes together to support the person who was chosen by the majority of the voters, or was selected as a compromise by the majority of delegates when the voters do not choose a majority leader.
If the "rule" is to become, as many Trump supporters argue now, that the guy with the "most" votes should win even if he doesn't have a majority, then the future races will be different.
Rather than work to find the one candidate that a majority can support, we will see further splintering. The goal becomes just "win more than everyone else," not "win the approval of more than half." Candidates will stay in the race longer and try to block each other more.
It will be about having the biggest faction, not about getting the candidate who can be approved by all.
