Commentary: Why the GOP can’t take the nomination from Donald Trump
However, if Trump arrives in Cleveland having won the most votes, the most contests, and the most delegates — all of which is very likely — depriving him of the nomination would be an unprecedented move in the modern political era.
Democrats, 1952. Tennessee Sen. Estes Kefauver came into the convention with more delegates than any other candidate, but short of an outright majority. He also came into the convention with a spotless reputation for being against corruption, which was a non-starter in the Democrat Party. So, the party bosses scammed him out of the nomination and handed it to Illinois Gov. Adlai Stevenson.
Ironically, four years later, the party nominated Stevenson again, on far more fair circumstances, and Stevenson let the convention pick his running mate. Guess who.
