Here’s an article worth your time from the New York Times of March 5, 2019 by Columbia Law Professor, Tim Wu: “The Oppression of the Supermajority.” https://www.nytimes.com/2019/03/05/opinion/oppression-majority.html?smid=nytcore-ios-share
The subtitle of the article sums it up very nicely: “The defining political fact of our time is not polarization. It’s the thwarting of a largely unified public.”
The article goes on to cite many public policy positions about which a supermajority of voters are in agreement but which our politicians prefer to turn into wedge issues. Given the structure of our election system, where a small group of highly engaged primary voters can determine who will represent a given district or state in Congress, members of Congress from both parties often prefer not to resolve such issues. They serve a more politically productive purpose for incumbents by energizing primary voters at election time.
The Public Check on Congress collective accountability mechanism would resolve this problem by creating a new, strong incentive for bipartisan and bicameral compromise.
