Gov. Mark Dayton and U.S. Sen. Al Franken picked up an early union endorsement.

The Minnesota AFL-CIO General Board voted to back the two Democrats for reelection, saying both were strong advocates for working Minnesotans.

"As governor, Mark Dayton is working to build a better Minnesota through successful job creation strategies, restoring fairness to our tax system, strengthening education, and supporting the rights of working people to bargain collectively," said Minnesota AFL-CIO President Shar Knutson.

"Al Franken, with a 98 percent AFL-CIO voting record, has demonstrated time and time again that he can be counted on to be a champion for working families in the United States Senate," she said.

Both candidates have relied heavily on union support in the past, both money and manpower. In past elections, Minnesota's union members put in thousands of hours on the phone and at the door, volunteering to help elect endorsed candidates.

The AFL-CIO elected board represents more than 300,000 union members throughout the state of Minnesota.
