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."
