While gerrymandering is done in congressional districts, it is not done with respect to the Senate. The entire state votes for senators. No Gerrymandering involved.
I stand corrected. Of course you are right, but it does not gainsay the fact that this Senate is comprised of aging nitwits and bloviators. As for the House, I believe you would admit that it has been Gerrymandered to the extent that very few seats now offer any competition.
