Republicans -- 95 delegates
Donald Trump is in an Empire State of Mind and is expected to cruise to victory here, but with his campaign in a state of turmoil he needs an overwhelming delegate triumph to improve his path to the GOP nomination. (Witness his delegate problems in Georgia and elsewhere.)
The number to watch is 50.
New York awards 14 statewide delegates and three per congressional district. In each case, 50 percent of the vote wins the whole pot. It's not a far-fetched number for Trump statewide, but John Kasich and Ted Cruz can make runs at him in some districts to tear down his delegate haul.
Highly educated Manhattan is tougher territory for Trump than downscale, heavily Italian-American Staten Island. Cruz and Kasich have concentrated their visits on upstate towns where Trump has not been a tabloid fixture for decades.
If Trump walks away with 85 delegates, it would be a major boost to his chances to wrap up the nomination before Cleveland.
Democrats -- 291 delegates
Bernie Sanders wants to be a part of it, and he has shown no signs of going away after Hillary Clinton seemed to have an insurmountable lead for the nomination. The delegate math still does not favor Sanders, but an upset here would be a shocking blow to the Clinton juggernaut.
There are a whopping 44 New York superdelegates -- and you can guess where most of them are aligned -- then 84 will be awarded proportionally statewide, with the remainder by congressional district. Sanders drew a massive crowd to Brooklyn's Prospect Park, but the closed primary favors Clinton, as many of the people feeling the Bern are not pre-registered Democrats.
Analysts are setting the bar for Clinton around a 10-point win: Hit that mark, and her march to the nomination continues. Anything tighter and Sanders can claim continued momentum and mitigate his delegate losses.
