A few updates since this thread has had none for months:
The legislature had a deadline of September 15, 2021 to submit a congressional map.
This did not happen, therefore a backup commission had until November 30 to finalize a map.
This did not happen, so the commission asked the CT Supreme Court for an extension on the deadline.
On December 9, the court granted their request, extending the deadline by three weeks to December 21, 2021.
Today is December 21, we shall see if the congressional map is actually finalized.
Connecticut DID however complete their maps for the state house and senate, and those can be found here:
