"So far, I'm really on my way," Trump told CNN after he netted back to back wins in South Carolina and New Hampshire following a close second-place finish in the Iowa caucuses.
Trump's win today gave him a critical burst of momentum heading into Nevada's Republican caucuses on Tuesday.
When asked if a strong opposition inside the party against him would result in a brokered convention in Cleveland, Ohio in July, Trump said he doesn't think "we're going to have a brokered convention. I think it is unlikely."
"I think most of the smart people are saying there's not going to be a convention. Interestingly, the ones who say there's going to be a convention, usually, they are the pundits that have been wrong forever, the ones that have been wrong about me," he said.
