Gerrymandering is as old as the republic. BOTH sides gerryamnder, some more than others.

Finally, there’s one important caveat to keep in mind regarding all of this, and that is that the scores presented above merely reflect imperfect estimates of the degree of gerrymandering in each congressional district. As such, a state not included among those at the top of the list might nonetheless possess districts that have been intentionally drawn to favor one political party over the other. Political activists therefore shouldn’t assume that places like Maryland, West Virginia, and Louisiana are the only battlegrounds states that matter in this fight, and that gerrymandering is less of an issue than it used to be in states such as North Carolina, for instance.
