US Republican presidential front-runner Donald Trump predicted matching up to Democrat presidential hopeful Hilary Clinton at the US general election come November, saying they would bring about “the greatest turnout in history.”

“I think it’s going to be Hillary and myself,” he said in an interview with Jake Tapper on CNN’s “State of the Union” on Sunday. “Frankly, if she gets indicted, that’s the only way she’s going to be stopped.”

The predictions followed Trump’s victory at the South Carolina primary and Clinton’s at the Nevada caucuses. However, on CBS’ “Face the Nation,” Trump said he would not be surprised if he doesn’t make it to the final GOP nominations.

“Look, I’m competing against professional politicians, senators, top of the line,” the Yahoo News quoted the real estate mogul as saying. “I know Ben Carson is still in it. He’s a terrific guy. A talented guy. So I’m competing against a lot of really good people.”

Trump added during the interview with Tapper that, he is expecting to win enough delegates to secure the party’s nomination before its convention in July. He predicted that he will win states that the Republicans never even thought of winning and that he will earn a great support from the African-Americans.

“I’m going to do great with the African-Americans. African-American youth is 58% unemployed. African-Americans in their prime are substantially worse off than the whites in their prime, and it’s a very sad situation,” the CNN quoted him as saying.

Clinton told during her part of the “State of the Union” interview that she is not yet thinking of a possible face-off with Trump and that she has a lot of work to do to convince people of her reliability and potentials.

“I understand that voters have questions — I’m going to do my very best to answer those questions. I think there’s an underlying question that maybe is really in the back of people’s minds, and that is, ‘Is she in it for us or is she in it for herself?’” Clinton said.

She added, “I think that’s a question that people are trying to sort through. And I’m going to demonstrate that I’ve always been the same person, I’ve always been fighting for the same values, fighting to make a difference in people’s lives, long before I was in elected office, even before my husband was in the presidency.”
