General Election, November 6, 2018

Missouri held its general election on November 6, 2018, deciding 180 legislative seats and the office of Auditor. No chamber changed party control.

Highlights

• Republicans kept their legislative supermajorities, but voters went against GOP leaders on several ballot measures, including the minimum wage in November and right-to-work in August.
• State Auditor Nicole Galloway (D) beat Saundra McDowell (R) by about 6 points in her first election since her 2015 appointment, leaving her the only statewide Democrat once Sen. Claire McCaskill lost her U.S. Senate seat the same night.
• Voters decided 7 measures in November, approving 4 and rejecting 3:
  • Amendment 1, the Clean Missouri initiative, tightened limits on lobbyist gifts and campaign donations and handed legislative mapmaking to a demographer nominated by the auditor; critics said it was meant to favor Democrats. Republican lawmakers put a rollback on the 2020 ballot, and voters scrapped the demographer plan before it was used.
  • Amendment 2 legalized medical marijuana. It was the only one of three competing proposals to allow home growing; the other two, Amendment 3 and Proposition C, failed.
  • Proposition B will raise the minimum wage to $12 an hour despite opposition from top Republican lawmakers.
  • Proposition D, a fuel tax increase for roads and bridges, failed despite bipartisan support from state officials.
  • Amendment 4, on bingo games, passed.
  • In August, voters rejected Proposition A, which effectively killed the right-to-work law the Republican legislature passed in 2017.
• In the legislature, 6 House seats changed hands, split evenly between the parties, and no Senate seat changed parties. Of the 3 incumbents who lost, two were Republicans unseated by Democrats: Matt Sain (D) beat Rep. Kevin Corlew (R) in House 14 by 85 votes, and Paula Brown (D) beat Rep. Mark Matthiesen (R) in House 70 by about 110. On the other side, Mary Elizabeth Coleman (R) unseated Rep. Mike Revis (D) in House 97. The only non-flip race inside two points was House 65, which Rep. Tom Hannegan (R) held by about 300 votes over Bill Otto (D). Elsewhere, 41 legislative races had only one candidate on the ballot.
