All of Missouri's expected U.S. Senate and gubernatorial candidates have filed to run for office.
Republican incumbent U.S. Sen. Roy Blunt and his Democratic challenger, Secretary of State Jason Kander, both officially entered the race Tuesday.
It was the first day candidates could file to run for public office, with filing ending on March 29.
All four Republican contenders to replace term-limited Gov. Jay Nixon also filed. Those candidates are suburban St. Louis businessman John Brunner, former Navy SEAL officer Eric Greitens, former U.S. attorney and state House speaker Catherine Hanaway, and Lt. Gov. Peter Kinder.
Democratic Attorney General Chris Koster also officially entered the race for governor.
