Only 32% of New York state voters have a favorable view of Senate Minority Leader Chuck Schumer — his lowest approval rating in 21 years of surveys conducted by Siena College.

A whopping 55% of respondents in the new Siena poll said they had an unfavorable view of the Senate Democratic leader.

Schumer’s rising unpopularity comes as ascendant left-wing Democrats have called on the longtime New York lawmaker to step down amid fury over not winning concessions from President Trump and Republicans to end the record-breaking government shutdown.

Schumer was viewed negatively by virtually every demographic group — liberals and moderates as well as conservatives, voters of all ages, from all regions of the state and both sexes.

His support was split among registered Democrats — 45% to 43%.

The lone bright spot for Schumer was among black voters, with 59% viewing him favorably compared to 22% who didn’t.

But 63% of white voters and 58% of Hispanics gave him a thumbs down.

Jewish voters were also meh on Schumer, with 46% of the faith viewing the proudly Jewish senator favorably and 47% unfavorably.

Schumer, 74, has been a force in New York politics for five decades.

He’s held public office since the 1970s — first as state assemblyman, then as a Brooklyn congressman before being elected to the US Senate in 1998.

That makes his plummeting stock all the more stunning.

“In February 2005 – the first Siena Poll in its current incarnation – Schumer had a 63-20% favorability rating.

In July 2005, he had his all-time best favorability rating, 70-22%,” said Siena College pollster Steven Greenberg.

“In February 2005 – the first Siena Poll in its current incarnation – Schumer had a 63-20% favorability rating.

“Schumer is viewed unfavorably by a plurality of New York City voters, and strong majorities of downstate suburbanites and upstaters,” Greenberg said.

The survey also noted that lefty democratic socialist firebrand “Squad’ Rep. Alexandria Ocasio-Cortez is more popular than Schumer.

Some lefty allies are urging AOC to challenge Schumer in a Democratic primary if he decides to seek re-election in 2028.

“It’s worth noting that Rep. Alexandria Ocasio-Cortez has an overall 42-37% favorability rating.

But it’s 62-20% with Democrats and 55-27% with City voters,” Siena’s Greenberg said.

By comparison, only 38% of Big Apple voters have a favorable view of Schumer, while 48% have a sour view.

This Siena Poll was conducted November 10-12 among 802 NYS Registered Voters.
