However, with Barack Obama 's razor thin defeat in 2008, the state began a rightward trek. In 2016, President Donald Trump won it by almost 20 points. 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 and the Show Me State 's reddening landscape have given Republicans cautious optimism, 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.
