Bob Burns signed up to run as a Democrat in the 93^rd House District as filing for that seat stayed open a little longer after state Rep. Scott Sifton (D-Affton) withdrew from that contest to run for the 1^st Senate District seat.

Burns was a major player in the effort to dissolve the tiny south St. Louis County municipality of St. George. He has served on the Affton School Board, worked as a staffer for Claire McCaskill and previously ran for the state House in the 2000s, losing narrowly to then-state Rep. Jim Lembke (R-Lemay). 

Other candidates in that contest include Democrat Joe Montecillo—husband of state Rep. Genise Montecillo (D-Affton)—and Republican Tony Leech. The winner of the Democratic primary in the 93^rd District, which includes a big chunk of Lemay, could be the favorite in the November election.

Burns also ran for the Subdistrict 3 seat on the St. Louis Community College Board of Trustees in the April 3 election. He lost to Joan H. McGivney by less than 30 votes.
