Don't expect to see Donald Trump give a humble concession speech if he loses the Republican presidential nomination.

During a Sunday rally in Maryland, the Republican presidential frontrunner mocked candidates who praise their opponents during concession speeches, saying that if he lost the contest, Americans would probably not hear from him.

"They fight like hell for six months, and they're saying horrible things, the worst things you can imagine," Trump said. "And then one of them loses, one of them wins. And the one who loses says, 'I just want to congratulate my opponent. He is a brilliant man, he'll be a great governor or president or whatever.'"

He continued: "I'm not sure you're ever going to see me there. I don't think I'm going to lose, but if I do, I don't think you're ever going to see me again, folks. I think I'll go to Turnberry and play golf or something."
