Mapping Early American Elections


17th Congress: Illinois 1820

Illinois elected one Democratic-Republican to the Seventeenth Congress.

Illinois used a statewide at-large system for electing members to Congress.

District Candidate Party Vote Percentage Elected
At-large Daniel P. Cook Democratic-Republican 5,322 69.3%
At-large Elias K. Kane Republican Faction 2,358 30.7%

In most cases, only candidates who received more than 5 percent of the vote in a district are reported. Other candidates are reported as a group, but only if they in aggregate received more than 5 percent of the vote. In addition, percentages for each district may not add up to 100 percent due to rounding. The term Dissenting Republican includes various breakaway factions of the Democratic-Republican party.
