Hamilton County is divided into twelve townships:
Like most of Southern-leaning Southern Illinois, Hamilton County was heavily Democratic before the Civil War, and unlike such counties as Johnson, Pope and Massac, it did not turn Republican after the war. Not until 1920, when isolationist sentiments turned many voters against the party of Woodrow Wilson, did Hamilton County vote Republican, and Herbert Hoover was to carry the county in 1928 due to anti-Catholic sentiment against Al Smith.
From 1940 onwards, when Wendell Willkie carried the county due to opposition to involvement in World War II, Hamilton has become increasingly Republican. Although Lyndon Johnson, Jimmy Carter in 1976 and Bill Clinton in 1992 all gained absolute majorities for the Democratic Party, since 1992, as with all traditionally Democratic parts of the Upland South, a very rapid swing to the Republicans has taken place due to overwhelming local opposition to the Democratic Party's liberal views on social issues.
