Given their first chance to score points head-on in their primary election battle, DFL gubernatorial candidates instead trained their fire Sunday on newly endorsed Republican candidate Tom Emmer in a debate on environmental issues.
Emmer was invited but did not show for the event. But former U.S. Sen. Mark Dayton and former House leader Matt Entenza, both DFLers, made sure that he wasn't forgotten.
"I think it's instructive who's not here today, the endorsed candidate of the Republican Party," Dayton said. "Environmental protection should be and used to be in Minnesota a bipartisan or nonpartisan concern, shared by everyone."
It was almost easy to overlook the fact that before DFLers can sink their claws into Emmer, they first face a contest of their own in the August primary that includes party-endorsed Margaret Anderson Kelliher, the House speaker.
Rob Hahn and Tom Horner, contenders for the Independence Party endorsement Saturday at the party convention in Bloomington, joined the three DFLers for a debate sponsored by Minnesota Environmental Partnership at the State Fairgrounds.
Kelliher left the debate after 40 minutes to attend the annual MayDay parade in south Minneapolis. Independence Party candidate businessman John Uldrich did not participate.
About 200 to 300 people attended the two-hour forum, which featured videotaped questions from Minnesotans.
Entenza turned one of the questions, about protecting water quality in Lake Superior, into a shot at Emmer.
