Can Trump be stopped in the GOP race?

Donald Trump won Florida, Illinois, Missouri and North Carolina. John Kasich won his home state of Ohio. Ted Cruz didn't win any states. With Trump failing to win Ohio there is still a chance that Cruz and Kasich can keep him under the number of delegates needed to clinch the nomination. However, with Cruz not picking up any other states, this is looking less likely. What do you think? Can Trump be stopped? Or is this race over? Jump In to the conversation and vote:
