HEMPSTEAD, N.Y. (CBSNewYork) — With just over two weeks before the New York presidential primary, Republican candidate John Kasich campaigned on Long Island Monday.

Kasich took part in town hall meetings at Hofstra University in Hempstead and at The Paramount in Huntington on Monday.

Back in Wisconsin, which votes Tuesday, Kasich’s rival Donald Trump said the Ohio governor should leave the race.

“You shouldn’t be littering up the process because that’s what he’s doing. It’s literally a disgrace, I’ll tell you,” Trump said.

Kasich responded on Twitter saying, “That’s not how our republic works, Donald. We’ll keep fighting until someone reaches a majority of delegates.”

Trump’s remarks went on to capture much of the focus at the event when Kasich appeared at Hofstra.

Kasich said he has the polls on his side, WCBS 880’s Mike Xirinachs reported.

“There’s a poll that came out today that shows me beating Hillary by 14 points in Wisconsin,” Kasich said. “How do we go to a convention and they pick somebody that can’t beat Hillary?”

Kasich called smear campaigns against him disgraceful, and laughed at the call for him to leave the race.

“They sure are worried about me, spending a lot of money to knock me out. But they’re not going to be successful in that,” Kasich said.

Trump will hold his first Long Island rally on Wednesday.

A CBS News tracking poll shows Ted Cruz leading Trump by five points with Kasich far behind.

On the Democratic side, the poll shows Bernie Sanders two points ahead of Hillary Clinton, who is appearing at a rally Monday to celebrate the New York Legislature’s recent passage of the $15 minimum wage and paid family leave.

Clinton and Bernie Sanders agreed Monday evening that they would hold a debate April 14 in New York, five days before the state’s April 19 primary.

Clinton reluctantly agreed for a face-to-face with Sanders in New York. She is looking to maintain her double digit lead in the polls in her adopted state.
