who is running for us senate in missouri
United States Senate election in Missouri, 2018 Incumbent Democrat Claire McCaskill is running for reelection, but is seen by many pundits as a vulnerable incumbent, as only 46% of her constituents approve of the job she is doing in the United States Senate. McCaskill's slightly unpopularity[2] and the Show Me State's reddening landscape have given Republicans cautious optimism[3], despite McCaskill's double digit victory in 2012. Missouri Attorney General Josh Hawley is seen as a favorite to challenge her by many GOP donors.[4][5][6]
