The arrogance of the GOP and their dismissal of the base is a powder keg.
I would not support it but would not be at all surprised if there were violence against the elites.
You assume you know who “the base” is. The GOP has had a big tent philosophy for decades and has produced a hybrid party with multiple bases. You may be correct that there is a violent Trump base that is loud and demanding, but I guarantee the party is hearing plenty from other “bases” within the party who will not vote for Trump. They are just as determined as the Trump crowd.
This is why someone must get a majority of delegates not just a plurality. If Trump wins on the first ballot fine. If not the rules change for ballot two and three if someone wins a majority fine. If it goes longer fine. If the delegates change the rules fine. We did a State Convention that went 12 Ballots and 17 hours in 2002. I suggest you bring snacks. It could be a very long night.
