Sen. Andrew Koenig returns to Politically Speaking to talk with St. Louis Public Radio’s Jason Rosenbaum about his re-election campaign in Missouri’s 15th Senate District. Koenig represents cities like Ballwin, Manchester, Valley Park and Kirkwood. He’s squaring off against state Rep. Deb Lavender, D-Kirkwood, in a contest most observers believe is the most competitive legislative race in the state this year.
