Here's a handy guide to the various Illinois congressional remap proposals released so far. For any proposal that included a GIS version of their map (Google Maps, KML, shapefile) I calculated the historical vote totals from 2016, 2018 and 2020 using the precinct total shapefiles from the Harvard dataset. Not all proposals included that kind of map so I wasn't able to perform that calculation for all.
Proposals submitted to the Illinois General Assembly portal can be found here.
Data for the current map (2011 - 2021) can be found here.
