Democratic congressional candidate Zephyr Teachout holds a double-digit lead in her primary contest against Will Yandik, an exclusive Time Warner Cable News/Siena College poll found.

On the Republican side, former Assembly Minority Leader John Faso also holds a double-digit lead against his challenger, businessman Andrew Heaney, for the GOP nomination in the 19th congressional district, the poll found.

Teachout, a Fordham Law School professor, draws support from 53 percent of registered Democrats, while Yandik, a deputy supervisor in Livingston, has 23 percent among likely voters. At the moment, 24 percent of voters have not made up their mind or have no opinion.

In the Democratic primary, 50 percent of voters say they are “absolutely certain” they have made their selection for the upcoming race. Of those voters, 53 percent say they are voting for Teachout, while 42 percent back Yandik.

Teachout is making her second run for elective office, having run for the Democratic primary for governor in 2014 against incumbent Andrew Cuomo. Teachout has sought to court county party leaders as well as those who support Vermont Sen. Bernie Sanders, who has a 72 percent favorable rating among Democratic voters polled in the district. Hillary Clinton, however, is virtually tied in favorability at 76 percent.

Yandik still has some work to do on his name identification: 53 percent of voters say they don’t know or have no opinion when asked if they have a favorable impression of him.

On the Republican side, a heated primary battle has erupted between Faso and Heaney.

Faso leads Heaney 50 percent to 28 percent among likely Republican voters, while 23 percent responded don’t know or have no opinion.

Forty-seven percent of GOP primary voters have a favorable view of Faso, while 30 percent hold an unfavorable view. For Heaney, he is underwater: 29 percent hold a favorable view; 45 percent take an unfavorable view of him.

Faso has slammed Heaney for donating to President Obama’s first campaign in 2007, while Heaney has sharply criticized Faso for his work as a lobbyist after an unsuccessful run for governor in 2006 against Eliot Spitzer.

Faso has sought to line up support from county leaders, while Heaney has eschewed that process in the lead up to the primary while also embracing Donald Trump’s presidential campaign.

Trump is popular in the district, with 65 percent of Republican voters holding a favorable opinion of him, while 31 percent hold an unfavorable view.

A plurality of voters, 47 percent, say they are absolutely certain who they are going to vote for in the GOP primary.

Rep. Chris Gibson, a Republican first elected in 2010, is retiring from the Hudson Valley congressional district at the end of the year. After initially testing the waters for a gubernatorial run, Gibson has decided to take a teaching job at Williams College in Massachusetts.

The 19th congressional district has been considered a key battleground for House races and has drawn national attention for the amount of money poured into campaigning in part due to no one media market dominating the area.

Gibson remains popular in the district among Republicans and Democrats alike: 86 percent of GOP voters hold a favorable view of him, as do 60 percent of Democrats.

The poll of 431 likely Democratic primary voters was conducted from May 31 through June 2 and has a margin of error of 4.7 percent. The poll of 436 like Republican voters has a margin of error of 4.8 percent.
