Political culture As a county anchored by a college town, Boone holds a Democratic tendency at the local, state, and federal levels. It is the only Democratic stronghold in Missouri outside of
Greater St. Louis and the
Kansas City metropolitan area. Boone County is also very progressive on ballot measures, voting for
Medicaid expansion in 2020 and
legal abortion in 2024, unlike all of its neighboring counties. Both amendments only narrowly passed statewide, making Boone County's votes crucial. No Republican has won Boone County at the presidential level since
George W. Bush very narrowly did in
2004, let alone with a majority since
landslide victor
Ronald Reagan in
1984; at the U.S. Senate level since
Roy Blunt in
2010; nor at the gubernatorial level since the popular
John Ashcroft (who won the county both terms) in his
1988 landslide re-election.
Local Like nearly all other U.S. counties housing a major university, the
Democratic Party predominantly controls politics at the local level in Boone County. Democrats currently hold all of the elected county-wide positions.
