New York primary day: Trump, Clinton win
Trump's victory was a psychological boost for his campaign, though the impact on his path to the GOP nomination was still to be determined by the number of delegates he secured. If he captured more than 50 percent of the vote, he would be in strong position to win most of New York's 95 delegates, an impressive haul. [CLICK HERE FOR LIVE RESULTS]
With the votes still being counted, Trump declared that it was "impossible" for his rivals to catch him.
"We don't have much of a race anymore," he said during a victory rally in the lobby of the Manhattan tower bearing his name. His peppered his confident remarks with more references to the economy and other policy proposals than normal, reflecting the influence of a new team of advisers seeking to professionalize his campaign.
Clinton's triumph padded her delegate lead over rival Bernie Sanders, depriving him of a crucial opportunity to narrow the margin. Sanders vowed to compete through all of the voting contests, though his odds of overtaking Clinton at this stage in the race are low.
"We've got a shot to victory," Sanders said in an interview with The Associated Press. "We have come a very long way in the last 11 months, and we are going to fight this out until the end of the process."
Sanders spent Tuesday in Pennsylvania, as did Trump's main rival Ted Cruz. The Texas senator panned Trump's win as little more than "a politician winning his home state," then implored Republicans to unite around his candidacy.
"We must unite the Republican Party because doing so is the first step in uniting all Americans," Cruz said in remarks read off a teleprompter.
The fight for New York's delegate haul consumed the presidential contenders for two weeks, an eternity in the fast-moving White House race. Candidates blanketed every corner of New York, bidding for votes from Manhattan and the surrounding boroughs to the working class cities and rural enclaves that dot the rest of the state.
Trump needed a strong showing to keep alive his chances of clinching the GOP nomination before the party's July convention — and to quiet critics who say the long primary season has exposed big deficiencies in his campaign effort.
Having spent months relying on a slim staff, Trump has started hiring more seasoned campaign veterans. He acknowledges that bringing new people into his orbit may cause some strife, but says the moves were necessary at this stage of the race.
Cruz is trying to stay close enough in the delegate count to push the GOP race to a contested convention. Cruz's campaign feels confident that it's mastered the complicated process of lining up individual delegates who could shift their support to the Texas senator after a first round of convention balloting.
Ohio Gov. John Kasich, the only other Republican left in the race, was seeking to add to his scant delegate total and keep up his bid to play a long-shot spoiler at the convention. Kasich has refused to end his campaign despite winning only his home state.
Trump's political strength, though he boasts of drawing new members to the party, has left some Republicans concerned that his nomination could splinter the GOP. Among Republican voters in New York, nearly 6 in 10 said the nominating contest is dividing the party, according to exit polls.
Trump leads the GOP race with 756 delegates, ahead of Cruz with 559 and Kasich with 144. Securing the GOP nomination requires 1,237.
Among Democrats, Clinton has 1,758 delegates to Sanders' 1,076. Those totals include both pledged delegates from primaries and caucuses and superdelegates, the party insiders who can back the candidate of their choice regardless of how their state votes. It takes 2,383 to win the Democratic nomination.
