MPR’s Art Hughes reports on Mayor Rybak’s desire to run again.

R.T. Rybak, mayor of Minneapolis, formally announced his re-election bid Sunday near the place he started his first campaign for elected office four years ago, almost to the day. At that time, he waged a grassroots battle against an established incumbent he felt was out of touch residents. Now, Rybak has a political track record that makes him the target for challengers. Report includes comments from Linda Longino, mother of slain child Tyesha Edwards; Don Samuels, City Council member; among others.
