One Senate seat is up for election in Missouri, held by a Democratic incumbent. Voters will also choose representatives for eight House seats, two of which are held by Democrats and six by Republicans. See Missouri’s primary results.
Sen. Claire McCaskill is one of the most vulnerable Democratic senators, but she has raised tens of millions for her reelection bid and polling shows a close race. State Attorney General Josh Hawley (R) softened his rhetoric on health care late in the campaign, although in 2012 he signed onto a lawsuit that would have repealed parts of the Affordable Care Act. Donald Trump won Missouri by about 19 points, and outside groups backing Hawley have spent big in this competitive race.
