The Missouri State Teachers Association has raised some concerns about claims used by one of the candidates in the race for the Democratic Party’s nomination for Lieutenant Governor. It says state senator Joe Maxwell’s claims that he has endorsements of some education groups might be misleading, because the MSTA does not endorse candidates. Maxwell defended his ads. He says they don’t advertise the endorsement of the MSTA, only the backing of many state educators. His opponent, state representative Gracia Backer calls the ads untrue.
