You can't blame the Framers for the filibuster

You can't blame the Framers for the filibuster "The Constitution didn't create the filibuster. The Framers didn't intend it. The modern filibuster was created in the 1970s, when cloture was moved from two-thirds of the Senate to three-fifths and dual-tracking was implemented, and it only became ubiquitous in the last 20 years, as you can see from the graph atop this post."
