What to look for ahead of Missouri’s primary election on Tuesday

Tuesday’s primaries could be one of the most important elections in Missouri’s modern history. Republicans will choose candidates for five statewide posts — including governor — who will be favored in November. Democratic voters will decide whether to send U.S. Rep. Cori Bush back to Washington and pick their candidates for U.S. Senate and governor. STLPR’s Sarah Kellogg and Jo Mannies join the “Politically Speaking Hour on St. Louis on the Air” to discuss the key races.
