Senator Sanders refused to request a recount citing concerns over wasting taxpayer dollars.

[7] Hillary Clinton, having narrowly lost the Missouri primary to Barack Obama eight years prior, managed a slim 0.2-percentage-point-victory over an increasingly popular insurgent Bernie Sanders in 2016.

Sanders was able to win 54-45 among union households, a key voting bloc in the industrial Midwest, and he won 53-46 among those who believe trade with other countries takes away U.S. jobs; trade deals championed by Bill and Hillary Clinton have not always gone over well in the industrial Rust Belt.

[11] Clinton won a large victory in St. Louis City and St. Louis County (she won 55-44 according to exit polls, likely thanks to her ardent African American support), and she also managed a 51-48 victory in Kansas City on the western side of the state.

Sanders, meanwhile, won victories in Columbia and Springfield, keeping the race close statewide, and won in the largely white, rural and more conservative counties, including areas of Northwestern Missouri bordering Kansas and Nebraska, and Southwestern Missouri bordering Oklahoma.
