Missouri held special elections on November 5, 2019, in six districts. In the 74th district, in Ferguson, the only candidates were a Democrat and a Libertarian. The Libertarian, Nicholas Kasoff, polled 42.7%. He had a fair amount of name recognition based on his previous campaigns for state and county office.
In the 22nd district, in Kansas City, the candidates were a Democrat, a Republican, and a Green, Jeff Francis. Francis polled 7.1%, which is the best showing ever for a Missouri Green Party nominee for federal or state office, in races with both major parties also in the race.
