Here are the Statewide election results for the 2016, 2018 and 2020 general elections by State House and Senate districts for the new maps:
Note: the General Assembly has amended the 2021-2030 map, this data has been updated to reflect the amended map passed on 09/01/21 by the ILGA.
To navigate to these datasets without direct links you can go: Home --> Analysis (top nav) --> Precinct Level Election Results --> View Statewide Race by Districts (Table View)
To get these totals I took the shapefiles of the new maps and intersected them with the shapefiles of the results of the 2016, 2018 and 2020 elections. For precincts that are now in more than one district I prorated the vote totals by the land area of the intersection, so if 40% of the land area of Precinct A was in District 1 then 40% of the vote totals of that precinct were assigned to District 1.
