NEW YORK (AP) - Democrats brawled in Brooklyn while Republicans in black tie threw sharp elbows at a Manhattan gala in a rowdy New York night of politics ahead of the state's Tuesday presidential primary.

As protests raged outside a state GOP dinner Thursday night, Republican front-runner Donald Trump delivered an impassioned defense of the city he calls home.Hillary Clinton and Bernie Sanders, meanwhile, aggressively challenged each other's judgment to be president at a raucous Democratic debate over Wall Street banks, minimum wage, gun control and foreign policy.The Democratic fight came at a pivotal moment in the primary campaign, with Clinton leading in the delegate count but with Sanders drawing intense enthusiasm. The debate left no doubt that a rivalry that once centered on wonkish policy disagreements has turned strikingly personal.
