Missouri Rep. Hartzler says she's not running for US Senate
Updated 11:59 am, Monday, July 17, 2017
Hartzler on Monday announced she's instead seeking re-election to the U.S. House.
Hartzler said she considered running, but believes that the race is for "another solid conservative to pursue and win."
McCaskill is among 10 Senate Democrats running in 2018 in states won by President Donald Trump. Republican U.S. Rep. Ann Wagner had been considered a potential front-runner candidate against McCaskill, but on July 3 announced she's also running for re-election to the House.
Several high-profile Republicans have also encouraged Missouri Attorney General Josh Hawley to run.
