I don’t believe many polls, but this one seems significant because there is little reason for them to skew the results this way. I’d expect to see disapproval numbers under 10%.
This probably happens all the time in the Senate. When he was just a Senator, Schumer could just represent the interests of his own constituents. As Senate Minority Leader, he becomes a national figure and comes off as a clown when he does stupid things like shutting down the government over illegal aliens who don’t even belong here.
