There should be serious consequences for any delegate bound to Trump that does not vote for Trump. Serious meaningful consequences upon their return to their home towns. Their neighbors did not sent then to Ohio to “vote their conscience” they were sent to represent the voters that choice Trump to be the GOP nominee. Betray that trust and bad things should happen to you when you get back home.
By the time the “consequences” kick in, the damage shall have been done. The Republicans lack the necessary party discipline apparatus to have the dissidents summarily ejected from the floor of the convention, and the substitute slate put in as the representatives of the outcome of the vote in that particular state.
“Representative republic” is supposed to define the form of committees adopted by custom and tradition, but it seems to be undergoing a redefinition at the moment.
