With 31 percent of the vote counted, Trump led with 62 percent, well ahead of the 50 percent figure he needs to claim all of the 95 New York State delegates to the Republican National Convention in Cleveland, Ohio in July.
However, Trump also needs to maintain a 50 percent vote share in every one of the state’s 27 congressional districts to sweep all the delegates.
Ohio Governor John Kasich trailed far behind with 26.6 percent of the vote and Senator Ted Cruz is a distant third with only 14. 4 percent.
In his victory remarks, Trump claimed that Cruz was now "just about mathematically eliminated" from getting more votes than him before the national convention to choose the Republican presidential candidate.
Earlier, NBC News/Wall Street Journal/Marist poll revealed that more than half of likely New York State Republican voters say they support billionaire businessman Trump, followed by 21 percent who support Ohio Governor John Kasich and 18 percent who favor Texas Senator Ted Cruz.
