In an April 2021 Monmouth University survey, an equal 34% of Americans approved and disapproved of the filibuster respectively, with another third saying they didn't have any opinion.

In the Monmouth survey, just 19% of Americans called themselves very familiar with the filibuster, with 4 in 10 saying they weren't too familiar with it or hadn't heard of it at all.

And in a 2018 Pew Research survey, just 41% of Americans knew that 60 votes were needed to end a filibuster in the Senate, contrasting with the broad majorities who correctly answered questions on the role of the First Amendment or the Electoral College.

Americans who do hold opinions on the filibuster are generally divided along partisan lines, with Democrats far more likely than Republicans to support ending it.
