Alliance for a Better Minnesota, a labor and DFL supported group, hasn't been kind to Republican Tom Emmer in its ads.
And sources say the group has a new television ad coming out next week that will be even tougher. One source described the coming ad as "bruising."
ABM won't be alone in unveiling a new ad soon. DFL Mark Dayton will also have new television ad out next week and the other DFL contenders in the Aug. 10 primary -- Matt Entenza and Margaret Anderson Kelliher -- likely won't be far behind.
