There was an interesting new post on the subject written by Richard Pildes and published at Election Law Blog. Pildes is well-known as a leading scholar of constitutional law. He posted this bit today:

Just ran across this story on the 12 most gerrymandered House districts, according to some experts The Fulcrum surveyed in 2019. Here is the comment on this district, OH 9, from Jason Fierman, founder and managing director of The Redistrict Network:

Ohio’s so-called “snake by the lake” 9th District, which stretches from Toledo to Cleveland, is so thin and strangely shaped that they actually drove to Lake Erie to monitor sea levels with respect to the contiguity of the district. They are concerned that climate change could make the district non-contiguous and consequently altered in the next round of redistricting.
