Noon update:

One of the state’s biggest unions today endorsed House Speaker Margaret Anderson Kelliher for Minnesota governor.

The Minnesota Association of Professional Employees made that announcement, saying the Minneapolis Democrat is the most electable.

"We believe Speaker Kelliher’s proven leadership skills and her ability to manage the state in difficult times make her the strongest candidate,” union President Chet Jorgenson said. “Speaker Kelliher is willing to bring people together to solve problems in a crisis. She has a history of respect for state workers and the jobs they do."

Thirty-nine MAPE officials met with governor candidates for two days and picked Kelliher. The Union has more than 12,700 professional state employee members.

The state’s biggest union, AFSME Council 5, endorsed former Sen. Mark Dayton.

MAPE Executive Director Jim Monroe said all Democratic candidates and one Republican, Pat Anderson, opted to take part in the union’s interviews.
