Donald TrumpDonald TrumpDon’t let Congress throw away our right to health Win with the Mooch: Finally, a man in the White House Trump can trust Trump to hold rally in West Virginia MORE courted support in Indiana the day after his big win in the New York primary, telling voters there that he would bring back manufacturing jobs as president. 

"If I were president, Carrier would not be leaving Indiana. That I can tell you," Trump said during a rally in Indianapolis, his first in the state. 

"Do you like the idea of taxing the hell out of their air conditioners?" Trump asked the crowd, adding, "you're going to pay a damn tax when you leave this country." 

Trump in his stump speeches has often mentioned Carrier air conditioning and its recent relocation of thousands of jobs to Mexico, but the issue hits home in Indiana, which is the leading manufacturing state in the country. Carrier's Indianapolis plant announced in February it would close and outsource 1,400 jobs over the next three years.  

Indiana is another crucial state for the businessman as he seeks to reach the 1,237 delegates necessary to clinch the GOP nomination. The state votes May 3, with 57 delegates up for grabs. 

In a nearly hour long speech repeatedly interrupted by protestors, Trump told the crowd their vote would be the "most important vote they would ever cast."  

"Once you cast that vote, our country will start winning again," Trump said.
