Tarryl Clark continues to roll up the union endorsements. The latest is from the Service Employees International Union’s state council. About the only politically influential union that hasn’t yet backed Clark in her quest to unseat U.S. Rep. Michele Bachmann is Education Minnesota.

“Tarryl has worked hard in the senate representing working people in her district, and now finally the 6th Congressional District has an opportunity to have a congresswoman who works for the district and not for cable TV,” said Carol Nieters, Secretary Treasurer of SEIU’s state council, in a statement announcing the endorsement. “I volunteered for Tarryl in her senate race. When I went door to door in the district for Tarryl, one thing was clear: voters really like her. She’s proven she can win in a Republican leaning district.”

Clark is vying with Maureen Reed for the DFL endorsement.
