How Latimer defeated Astorino, by neighborhood: Map

State Sen. George Latimer defeated Westchester County Executive Rob Astorino on Election Day by out-polling the Republican incumbent in some of his most loyal election districts, a map of the results shows.

Latimer won northern Westchester towns that came out heavily for Astorino in 2013, including Cortlandt, Lewisboro and Pound Ridge, while taking larger portions of Republican strongholds in Yorktown, Somers and North Salem that Astorino won, according to the unofficial results.

The county's northeast quadrant had the largest shift from four years ago, when Astorino won his second four-year term by defeating New Rochelle Mayor Noam Bramson. This year, Astorino won only three election districts in Lewisboro and Bedford combined, and none in Pound Ridge.

The numbers show why poll watchers were able to call the race early as numbers from those districts began coming in on election night.

Republican strongholds in the lower portion of the county, including in Eastchester, Harrison and East Yonkers, remained loyal to Astorino.

Astorino also won his hometown of Mount Pleasant by a 59-41 percent margin.
