Republicans have lost the first election in Missouri since Eric Greitens resigned the governor’s post in disgrace, with Democrat Lauren Arthur picking up a state senate seat in the Kansas City suburbs.
With 100 percent of precincts reporting, Arthur had defeated Republican Kevin Corlew — a fellow state legislator — by 19 points. That represented a sizable swing toward Democrats in the 17th district, which backed both Donald Trump and Mitt Romney by 4 points.
