Expect to see more campaign ads in the race for Minnesota governor this week. Former U.S. Senator Mark Dayton unveils his first TV ad in the governor’s race at the Capitol today. Dayton is vying with House Speaker Margaret Anderson Kelliher and former legislator Matt Entenza in the August 10th Democratic primary. The nominee will face Republican Tom Emmer and probably Independence Party candidate Tom Horner in November. Entenza has been running TV ads for more than a month.
