To that point, a fascinating recent article on Politico.com is well worth a look for people who follow the gerrymandering issue.
It delves into a reference to James Madison, Father of the U.S. Constitution, that Supreme Court Chief Justice John Roberts made in his recent, landmark opinion on gerrymandering. Roberts alluded to Madison's own nearly catastrophic experience with attempts to tilt elections through the way district lines get drawn.
Roberts' opinion laid out the reasoninb behind the majority's decision that the high court had no "manageable," defensible way to intervene in cases where excessively partisan gerrymandering is alleged. He mentioned Madison's experience as evidence that gerrymandering has been around since the dawn of the Republic.
The Politico article lays out a case that the congressional election Madison almost lost due to gerrymandering was one of the most important in the nation's history. It suggests a very different interpretation can be put on Madison's experience than the one the chief justice offered. We suggest you give it a read.
