Democratic congressional candidate Zephyr Teachout on Friday was endorsed by the environmental group Sierra Club ahead of the Tuesday primary.

“New Yorkers can clearly see that Washington is broken, and right now we need someone who is willing to stand up to corporate money and toxic polluters to say enough is enough,” said Erin Riddle, who chairs the organization’s Atlantic Chapter.

“Zephyr’s commitment to our environment, public health, and democracy make her an ideal choice, and that’s why the Sierra Club is proud to endorse her for Congress.”

Teachout is running for the Democratic nomination in the 19th congressional district, a Hudson Valley seat that is being vacated by Republican Rep. Chris Gibson.

She faces Will Yandik, a deputy town supervisor in Livingstone, on Tuesday in a primary.

“I’m thrilled to have the support of the Sierra Club. After the historic victory to ban fracking in New York, I know we can take the fight to Washington and win,” Teachout said.

“Together we can stand up to the corporate lobbyists who want to pollute our resources, contaminate our water, and make a profit off our land. Organized people is the best defense against organized money.”

A poll released by TWC News/Siena College showing Teachout leading Yandik in the primary race by double digits.
