Harvard Journal of Law and Public Policy Article Shows How Filibuster Rule Can be Overcome by a Majority Vote

As noted below, one might argue that Congress will be unable to expand the U.S. Supreme Court, because opponents would filibuster such a law in the U.S. Senate (and supporters would not be able to muster 60 votes to invoke cloture to stop the filibuster).

This article shows how the U.S. Senate on several occasions has used a majority vote to eliminate the opportunity to filibuster. Ultimately, it only takes a majority vote to change the rules of the Senate, including the 60-vote cloture rule.
