MPR’s Tom Scheck reports on upcoming DFL battle for congressional seat. Ellison is the DFL-endorsed candidate for Congress in the Fifth Congressional District. Yesterday the former chair of the state DFL Party, Mike Erlandson, filed for the same seat. Erlandson is ignoring his party's endorsement and trying to beat Ellison in the September primary. Erlandson is getting help from his former boss, Congressman Martin Sabo, who is retiring at the end of the year.
