Nadler Routs Maloney in Marquee Showdown of Bruising New York Primaries

Representative Jerrold Nadler, the chairman of the House Judiciary Committee, handily defeated his longtime congressional neighbor,

Carolyn B. Maloney, in a bruising three-way primary battle on Tuesday that was preordained to end one of the powerful Democrats’ political careers.

The star-crossed skirmish in the heart of Manhattan was unlike any New York City — or the Democratic Party writ large — had seen in recent memory.

 Though few ideological differences were at stake, it pitted two committee chairs who have served side by side in Washington since the 1990s against each other, and cleaved party faithful into rival factions.

Allies had tried to pull Mr. Nadler off the collision course into a neighboring race after the state’s calamitous redistricting process unexpectedly combined their West and East Side districts this spring.

But he pushed forward, relying on his reputation as an old-school progressive and leading foil to Donald J. Trump to win over voters in one of the nation’s most liberal districts.

“Here’s the thing: I’m a New Yorker, just like Bella Abzug, Ted Weiss and Bill Fitts Ryan,” Mr. Nadler, 75, told supporters after his victory

referencing liberal lions who represented New York in Congress. “We New Yorkers just don’t know how to surrender.”
