The legislative filibuster has no constitutional roots. In fact, it has the opposite thereof. Treasury Secretary Alexander Hamilton wrote about the evils of supermajority requirements for legislative bills in the Federalist as a result of all the deadlocks that kept happening in the times of the Articles of Confederation. The filibuster accidentally emerged as a result of Vice President Aaron Burr, the guy who shot Hamilton, arguing that a Senate rule allowing senators to proceed to a vote by simple majority was redundant and unnecessary, and the senate subsequently eliminating the rule in compliance. Then history happened. The senate needs to undo the damage that Burr has done to its ability to conduct business and abolish this procedural obstacle out of existence.
