Sen. Chuck Schumer and Gov. Andrew Cuomo both took a slide and their sparring partner in the White House rose from the depths in polls of New York voters released by Siena College last week.Among New Yorkers polled by Siena, 52 percent had a favorable opinion of Schumer and 39 percent had a unfavorable view, the lowest he has scored since Siena first polled voters about him in 2005.
