Conservative radio host and debate moderator Hugh Hewitt asked Trump if it's "legitimate" for a candidate to become the nominee at the party's national convention if the GOP front-runner falls short of the 1,237 delegates needed for the nomination.
"If Marco, if the governor, if Ted had more votes than me in the form of delegates, I think whoever gets to that top position as opposed to solving that artificial number that was set by somebody which is a very random number, I think that whoever gets the most delegates should win," Trump said at CNN’s GOP debate in Miami.
"But if someone doesn't have the delegates, and I guess there's two of us up here that can and there's two of us who can't at this moment.
"That is not meant to be a criticism, that's just a mathematical fact," Trump added.
Hewitt also posed the question about the delegate math to Kasich, saying that the Ohio governor will not be able to mathematically capture the nomination unless it goes to a convention. But Kasich, who’s hoping to win his home state in Tuesday’s winner-take-all primary, brushed it off.
"Math doesn’t tell the whole story in politics," Kasich said. In school, he said, "if you got an 86, you got a B. Just because everybody else got an 84 doesn't mean you got an A. So you just have to win enough delegates to be the nominee," Kasich said.
"You have to earn the delegates in order to be picked, but let's not get ahead of ourselves. We don't know what's going to happen because we still have about half the delegates to be selected," Kasich added.
In the race for the 1,237 delegates needed to secure the GOP nomination, Trump leads with 458 delegates, followed by Cruz at 359, Rubio at 151 and Kasich at 54.
