Thanks to Matt Dietrich at the Illinois State Board of Elections and to Cris Cray who put these county by county totals together for the Election Assistance Commission and shared them with us.

Here you can find the historical totals for early vote, vote by mail, absentee, grace, provisional and same day vote totals, where available. For some years we have county by county totals with more granular data. This dataset is not perfect but it's a helpful guide and as far as I know it's all there is.
