Gov. Andrew Cuomo's primary win has fired up his GOP opponent Rob Astorino.

The Westchester County executive says the fact that Cuomo's primary challenger did better than expected Tuesday night speaks volumes.

Cuomo took 62 percent of the vote, beating out his primary threat Zephyr Teachout. It was not the landslide Cuomo had hoped for, however.

Teachout walked into the race a virtual unknown, was outspent 100-to-1 and was a complete long shot. She still managed to garner more than one-third of the votes statewide, even claiming victory in most of the Hudson Valley.

Cuomo's running mate, Kathy Hochul, from Buffalo, also won last night, beating out Columbia law professor Tim Wu.

Astorino is currently far behind in the polls and name recognition, but says Tuesday's primary proves anything can happen when voters head to the ballot boxes.
