Schumer isn't happy with legislating, being on committees, paying record-level fines for campaign finance violations and letting people get away with aggressive campaign fundraising in his name.
Schumer wants to do the President's job, too...selecting Federal Justices. That alone makes him the perfect example of a bossy liberal.
I have to give him credit for toning down the rude stage whispering he has done in the past while witnesses were testifying before the Senate Judiciary Committee. He and Feinstein couldn't keep from gabbing during the Ashcroft confirmation hearings. They were so loud that it was hard to hear the testimony.
