Hey Pollsters! Shouldn't we be seeing some work being done on public opinion of the filibuster? Right now, the fact of the filibuster, and Senate anti-majoritarian procedures in general, is a highly important issue, and yet as I look at pollingreport.com, the most recent polling on filibusters is from the "nuclear option" debate over judicial nominees in 2005 -- and those questions were specifically about the claim that those nominees should be exempt from normal Senate rules.
Granted, this is mostly Barack Obama's fault for not elevating the issue enough, but still: let's go, pollsters! Are Americans OK with the idea that 41 Senators can stop everything?
UPDATE: CNN has 56% in favor; John Sides at the Monkey Cage has details.
