Zephyr Teachout, the Fordham law professor who captured nearly a third of the Democratic primary vote against Gov. Andrew Cuomo in 2014, coasted to victory Tuesday in the 19th Congressional District primary.

Polls had shown Teachout, who enjoys high name recognition from her 2014 primary bid and her steady critiques of state government corruption, was expected to prevail over Columbia County farmer and Livingston deputy town supervisor Will Yandik and she did, netting more than 73 percent of the vote as of about 10:15 when she greeted a cheering crowd of supporters.

She arrived at the Senate House banquet hall in Kingston but was in seclusion for a good hour — reportedly waiting to make sure that GOP candidate John Faso had prevailed over his opponent Andrew Heaney. She also said she spoke with Yandik who conceded.

Teachout wasted little time launching into her campaign theme in which she promised to fight the Big Money-Lobbying culture that she said pervades Congress.

“We need people in Congress who are not for sale,” she told the crowd after being introduced briefly by Ulster County Democratic Executive Mike Hein, who at one point was the subject of a draft movement but declined to seek the Congressional seat.

She quickly launched an attack against her Republican candidate describing Faso as an “Albany insider” and “Creature of Albany.”

“John Faso is an Albany assemblyman-turned-lobbyist. He is the ultimate insider. He’s going to keep those doors closed and double locked. I’m going to break those doors down.”

Voters in the 19th C.D., which is being vacated by Republican Chris Gibson, will have a clear choice in the Teachout-Faso contest.

Teachout falls squarely in the progressive camp, with support of the Working Families Party while Faso has a long track record as a conservative.

While a vocal supporter of public campaign financing, Teachout has raised nearly $1.3 million as of early June, according to federal filings.

Many, though, are small contributions through ActBlue, a national PAC that supports Democrats.

Nationally, Democrats see the 19th District as obtainable, and they need to do well in New York overall if they want to dent the Republican’s dominance in the House.

Teachout has also received endorsements of U.S. Sen. Kirsten Gillibrand, who while in Congress represented an earlier iteration of the district before its once-a-decade reapportionment.

She’s has also gotten campaign donations from celebrities such as actor Mark Ruffalo and Ben Cohen, of Ben & Jerry’s fame.

Teachout moved from Brooklyn to Duchess County in 2015 and Faso, who has lived in the district for decades, will almost certainly attack her as a carpetbagger who was shopping for a Congressional district in which to run.

The 2014 Democratic candidate, Sean Eldridge, suffered from that criticism as he and his wealthy husband, Facebook co-founder Chris Hughes, purchased a multi-million dollar home in the district shortly before Eldridge’s disastrous run against Gibson.

After her victory speech, she deflected a question about the likely carpetbagger tag, saying that people are mostly looking for change and for a lawmaker who is tuned into their interests. “I think there is this anger,” she said.

Teachout has previously said she grew up in an area similar to the 19th CD in her native Vermont.

Her team maintains she picked up popularity starting with her 2014 gubernatorial bid, but Teachout’s candidacy also coincides with that of Bernie Sanders, a fellow Vermonter and progressive who had been challenging Hillary Clinton for the Democratic presidential nomination.

The Sanders phenomenon may have spiked interest in progressive ‘’outside’’ candidates and members of Teachout’s team here say they are drawing both Sanders and Donald Trump supporters.

Her supporters on Monday appeared to be a mix of 20-somethings and aging hipsters (Woodstock is only 11 miles from here on the back roads).

For the general election, however, she’ll have to reach far beyond those demographics in this sprawling exurban and rural district, punctuated by rust belt river towns like Kingston and Hudson where Faso and his supporters had gathered. Current Congressman Chris Gibson, a moderate Republican, carved out a reputation as a common sense, practical politician, dealing with some of the real-life problems of constituents.

“I have a lot of respect for Chris Gibson,” she said.
