The filibuster is not in the US Constitution. However, Senators have lately been abusing it in unprecedented amounts. If you are frustrated with the logjam in the Senate, take action by urging your Senators to seek meaningful reform. Also, visit Common Cause, which is working to fix the filibuster.
The nonpartisan Common Cause is also working to overturn the extremely harmfulCitizens United v. Federal Election Commission Supreme Court case that takes even more power from American citizens and gives it to corporations.
