With less than a month to go until the June 5th primary, the Democrat candidates for governor continued to make their case to voters. They debated in Davenport Sunday at an event hosted by KWQC-TV and the Quad-City Times. The candidates debated a number of topics, including mental health care, changes made last year to collective bargaining, and recent sexual harassment cases in the capitol. They also talked about helping rural Iowa by investing in those areas and making sure services like good hospitals and schools are provided.
