New York governor Andrew Cuomo won the state’s Democratic primary last night, but a relatively unknown law-school professor may still have dealt a blow to his national ambitions.

As of Wednesday morning, with 99 percent of New York precincts reporting, Cuomo has won just 62 percent of the primary vote. Zephyr Teachout, a Fordham law school professor, who has never run for office before and ran a bare-bones campaign, garnered 34 percent. A third candidate, Robert Credico, got about 4 percent of the vote of the vote, meaning almost 40 percent of New York Democrats voted for someone other than their party’s incumbent.

Teachout fared far better than expected, especially considering her limited resources and Cuomo’s huge fundraising operation, which shows some deep discontent on the left with Cuomo’s policies and cooperation with the state’s Republicans.

“Anything over 25 percent against an incumbent with 40 times as much money, one of the most famous names in politics, and a four year’s head start on me, I am really, really proud of what we did,” Teachout said in her concession speech.

This isn’t a good look for Cuomo, who’s said to harbor presidential ambitions. “Cuomo lost everything tonight except the nominaiton, “Teachout supporter and former NYC public advocate Mark Green said.

Cuomo will now face Republican candidate and Westchester County executive Rob Astorino in the November election. Astorino, despite trailing the governor by 30 points in the most recent poll, continues to say the race is winnable. During a radio appearance on Wednesday morning, he said that there is no excitement over Cuomo on the campaign trail — an understandable observation given liberal discontent with the governor and allegations, currently being investigated by federal prosecutors, that Cuomo interfered with and finally shut down a state anti-corruption investigation he’d pledged to support.

In July, Astorino told National Review Online, “The things I’m hearing from most people throughout the state . . . is a lot of people just feel like Cuomo hasn’t done anything. He’s not done anything to make it better.”
