Brookings County voters are reliably Republican. In only two national elections since 1932 has the county selected the Democratic Party candidate.
Typical of the Great Plains, Brookings County voters are reliably Republican, even for a county with politics influenced by a college town. In only two national elections since 1932 has the county selected the Democratic Party candidate. Despite being reliably Republican territory, no Republican has taken over 60% of the vote since Ronald Reagan in 1984.
