The location of the vote varies from year to year and has evolved over time as the population has shifted. Further, the noted difference in turnout between Presidential election years and non-presidential election years has an effect on the location of the vote. Below is a table that shows the vote share by region for the top ballot races in the last two cycles. The regions are defined as City of Chicago, the Cook County suburbs outside of Chicago, the five traditional collar counties (Lake, McHenry, DuPage, Kane & Will) and the downstate 96 counties.
