After the official results rolled in and revealed a demonstrative win in New York's Democratic primary Tuesday, the band at Hillary Clinton's victory party played Stevie Wonder's classic "Signed, Sealed, Delivered." The presidential hopeful and former secretary of state had locked  up New York and, with it, built what appears to be a nearly insurmountable delegate lead in the race for the 2016 nomination. 

As the New Yorker reported, Clinton's victory speech turned toward the general election and reached out to supporters of her competition, Vermont Sen. Bernie Sanders, saying, "I believe there is much more that unites us than divides us." She later added, "The race for the Democratic nomination is in the home stretch, and victory is in sight."

On the Democratic side, it takes 2,383 delegates to secure the nomination. Following New York's vote, in which Clinton garnered 58 percent support, the former secretary of state leads Sanders 1,446 to 1,200 in pledged delegates. She also has the support of 469 super delegates to Sanders' 31, according to the New York Times.

Clinton, who lives in New York and represented the state as a senator, took 139 delegates from the Empire State, compared with 106 for Sanders, who garnered 41.2 percent support. Sanders is not eliminated in mathematical terms, but his road toward a nomination narrowed significantly. Even before New York, it was an incredibly difficult task; the Vermont senator needed 68 percent of remaining delegates to mount a challenge.

Republican front-runner Donald Trump had a great day in his home state, registering 60.5 percent support and far outpacing Ohio Gov. John Kasich at 25.1 percent and Texas Sen. Ted Cruz at 14.5 percent. Trump took the lion's share of New York's delegates with 89, compared with three for Kasich and none for Cruz. Trump has earned 845 delegates overall, leading Cruz at 559, Kasich at 147 and the zombie-campaign of Florida Sen. Marco Rubio at 171. Trump would need to register 1,237 delegates to lock up the GOP nomination outright and prevent the expected contested convention. 

Following New York's vote, both Cruz and Sanders face steep challenges securing enough delegates for a pre-convention win. Wrote John Cassidy in the New Yorker, "Strictly as a matter of arithmetic, neither front-runner’s lead is insurmountable. But, practically speaking, it is now hard to see how either Cruz or Sanders could get enough delegates to win. Their hopes rest on turning things around at the conventions."
