State Sen. Tarryl Clark (D) continues to round up Democratic establishment support for her campaign to unseat Rep. Michele Bachmann (R) in Minnesota’s 6th District. The latest endorsement comes from Rep. James Oberstar (D), the powerful chairman of the House Transportation and Infrastructure Committee who has represented the neighboring 8th district for 18 terms.

“I’m proud to support my friend, Sen. Tarryl Clark, in her campaign for Congress,” Oberstar wrote in an e-mail to Clark campaign supporters, calling Clark “a seasoned, experienced legislator.”

Clark received the backing of freshman Sen. Al Franken (D-Minn.) last month and has also received a number of labor endorsements.
