After a nearly eight year hiatus, former Missouri state Sen. John Lamping returns to Politically Speaking to discuss this year’s unpredictable U.S. Senate primary. Lamping represented the 24th Senate district from 2011 to 2015. Since then, he’s moved to St. Charles County but knows many of the contenders to succeed U.S. Sen. Roy Blunt well. He noted that he hasn’t endorsed any of the candidates and doesn’t plan to at this point.
