The filibuster rule just isn’t very popular among those who know what it is. Pew found that 26% of Americans knew how many votes were needed to get around a filibuster. Zogby reports that 32% want to get rid of that anti-democratic blockage.
And these two polls were probably looking at samples of the same population, given Zogby’s findings confirming vast ignorance: Only 34% knew Republicans use the filibuster more. Only 28% knew the House represented public opinion better than the Senate.
