† county seat
Grundy County has long been one of the most consistently Republican counties in Iowa. The county has only voted for a candidate of a different party four times since the county was founded in 1851. The first occasion was in 1912, when former Republican Theodore Roosevelt won the county as the Progressive candidate. During his two landslide victories of 1932 and 1936, Franklin D. Roosevelt became the first Democrat to win Grundy County in its history. The final time a non-Republican candidate carried the county was in 1964, when Lyndon B. Johnson won in a nationwide landslide. No Democratic candidate has ever received more than 60% of the vote in the county, and in the last twenty elections (beginning in 1944), the Republican obtained at least 60% of the vote in fifteen of them, and the Republicans have hit at least 65% in nine of the twenty elections in that span.
