Connecticut passed their new state House of Representatives district plan on November 18, 2021 and passed their new state Senate district plan on November 23, 2021. Each passed unanimously in their 9-person bipartisan Reapportionment Commission; however, the process has been criticized for legislators controlling the process and for the negotiations that serve to protect incumbents. This paper investigates the extent of incumbent protection in the new Assembly maps while also providing summary data on the new districts. The impact of new districts on incumbents is analyzed through the location of district borders, an ensemble analysis (using MCMC methods) to determine if the protection of incumbents constitutes a statistical outlier, and by investigating changes to competitive districts.
