In this first of a series of columns, Illinois Law dean and professor Vikram David Amar offers four observations about recent calls for reform of the filibuster device in the U.S. Senate. Dean Amar suggests looking at state experiences with supermajority rules, as well as the Senate’s own recent past, and he considers why senators might be reluctant to eliminate the filibuster. He concludes with a comment on President Joe Biden’s suggestion that the Senate return to the “talking filibuster” and praises a suggestion by Senator Tom Harkin (D-IA) that the cloture requirement (currently at 60 votes) could be lowered gradually, the longer a measure under consideration is debated.
