 WEST PALM BEACH, Fla. — Donald Trump called on Republicans to rally around his candidacy Wednesday, and said there could be "riots" if the party somehow conspires to deny him the presidential nomination after he remains way ahead in convention delegates. "I think you'd have riots," Trump said on CNN. Noting that he's "representing many millions of people," Trump told host Chris Cuomo: "If you disenfranchise those people, and you say, 'I'm sorry, you're 100 votes short' ... Otherwise, he told CNN, "I think bad things would happen." (Jenny Starrs/The Washington Post) 
 
 The billionaire businessman emphasized, though, that he expects to secure the 1,237 delegates needed to win the party's nomination ahead of the Republican National Convention in July. [The Stop Trump movement’s last realistic hope is now a contested convention in Cleveland] 
 
 Trump woke up Wednesday with 621 delegates. In any event, the Republicans now have only a three-candidate race: Florida Sen. Marco Rubio pulled out Tuesday night after he lost his home state big to Trump. Republican front-runner Donald Trump spoke in Palm Beach, Fla., after primary voters took to the polls in five states: Florida, Illinois, Ohio, Missouri and North Carolina. He added: "We have to win, and as we win, people will forget and they will feel better.
– Donald Trump's campaign rallies have made headlines because of violence, but he suggests we haven't seen anything yet if the GOP somehow deprives him of the nomination at the convention. "I think you'd have riots," he said on CNN Wednesday, per USA Today and the Washington Post. "I'm representing many, many millions of people." Trump predicted he'd lock up the necessary number of delegates to secure the nomination anyway—"I'm a closer"—but he warned that the party will be flirting with trouble if it moves toward a brokered convention in the event he comes up shy. "If you disenfranchise those people, and you say, 'I'm sorry, you're 100 votes short' ... I think you'd have problems like you've never seen before. I think bad things would happen."
