Yeah. I was disappointed to see that there wasn't a comparison between 2011 and 2013 to try to identify how big that effect was. Wikipedia has images that can

Yeah. I was disappointed to see that there wasn't a comparison between 2011 and 2013 to try to identify how big that effect was. Wikipedia has images that can give a vague idea of the geographic shift (which I like especially because they show which districts flipped in the election). It looks to me that some of the major shifts were independent of gerrymandering (e.g. Dakotas becoming solidly Republican, Dem control solidifying over coastal Pacific and around NYC), while others might have been tied to it (e.g. compaction of Dem control in UT, AL, MS). 2010 election: https://upload.wikimedia.org/wikipedia/commons/thumb/a/ac/2010_House_elections.svg/400px-2010_House_elections.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/a/ac/20... 2012 election: https://upload.wikimedia.org/wikipedia/commons/thumb/b/b8/US_House_2012.svg/400px-US_House_2012.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/b/b8/US... 2018 election: https://upload.wikimedia.org/wikipedia/commons/thumb/4/48/US_House_2018.svg/400px-US_House_2018.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/4/48/US...
