Favorability ratings are slipping for the state’s two Senators, both of whom are on the ballot this fall.

In a Siena Research Institute poll released Monday, ratings have fallen for Democratic Sens. Charles Schumer and Kirsten Gillibrand.

“His 54-32 percent favorable rating marks the first time ever in a Siena College poll that less than 60 percent of voters have a favorable view of him and more than 30 percent view him unfavorably,” pollster Steven Greenberg said of Schumer.

A month ago, Schumer’s favorability rating polled 10 points higher, Greenberg added. Those surveyed favored Schumer 59 percent to 27 percent over former CIA Officer Gary Berntsen (R) and 60 percent to 26 percent over political consultant Jay Townsend (R).

Gillibrand was favored 48 percent to 27 percent over former state legislator Bruce Blakeman and 49 percent to 24 percent over economist David Malpass.

Gillibrand was viewed favorably by 36 percent of those polled. In May, 42 percent viewed her favorably.

Siena’s poll, conducted June 7-9, sampled the opinions of 808 registered voters. Its margin of error was 3.4 points.
