Missouri House of Representatives — District 124 — Miller County (2020)[14]
Like most counties in rural western Missouri, Miller County is very Republican. It hasn't supported a Democrat for president since Franklin D. Roosevelt in 1932. The only other time it supported a Democrat in the 20th century was in 1912, when Woodrow Wilson carried the county against a mortally divided GOP. Lyndon Johnson is the last Democrat to garner even 40 percent of the county's vote.
Underlining how Republican the county has been over the years, it rejected native son Harry Truman in 1944 as Roosevelt's running mate, and when he headed the ticket himself in 1948.
Former GovernorMike Huckabee (R-Arkansas) received more votes, a total of 1,406, than any candidate from either party in Miller County during the 2008 presidential primary.
