Local
The Republican Party controls politics at the local level in Platte County. Republicans hold all of the elected positions in the county. However, Governor Jay Nixon carried the county in his two successful elections, and in 2004, Claire McCaskill of Jackson County narrowly won a majority of the county's votes over Republican victor Matt Blunt. While the county has swung to the Republican party, the presence of Kansas City has helped keep the county competitive into the 21st century.
