Republican presidential candidate Donald Trump improved his chances of winning party nomination on Tuesday after securing a victory in the New York primary, while Democratic candidate Hillary Clinton stopped Senator Bernie Sanders's winning streak and took an important step toward clinching the nomination, the media reported.
Trump campaigned vigorously for a huge vote total to revive his political fortunes.
He drew support from majorities of nearly every demographic group across the state, according to exit polls by Edison Research, The New York Times reported.
Media declared Trump winner shortly after the polls closed. Early results with 40 percent of all votes counted show Trump won more than 60 percent, the report added.
Trump now has clear momentum heading into the next primaries in Pennsylvania, Connecticut and three other states on April 26.
His victory in his home state came well within expectation as early surveys over the past few weeks showed the current GOP front-runner led the Republican field with a large margin.
If voting for Trump tops the 50 percent mark statewide, Trump would take all 14 at-large delegates. The remaining 81 delegates would be allocated based on the share of votes in all New York's 27 congressional districts.
A clean sweep of all 95 New York delegates would be crucial for Trump, as he was seeking a path to garner 1,237 delegates before the contested party convention in July.
Trump entered the contest on Tuesday with 755 delegates, 212 more than his major rival Texas Senator Ted Cruz.
On the Republican side, Clinton held an edge in early returns even as Bernie Sanders, a US senator from Vermont, fought for an upset victory.
Early results with 55 percent of all votes counted showed Clinton led Sanders by about 20 percent.
After her win in New York, Clinton would take a majority of New York's 247 pledged delegates, further widening her delegate lead over Sanders.
Clinton entered the contest on Tuesday with a substantial edge over Sanders in terms of pledged delegates, with 1,411 to 1,179, according to the latest New York Times delegate count.
To win the party's nomination, a Democratic candidate needs to win over 2,383 delegates, including unpledged delegates, who at the moment overwhelmingly support Clinton.
