Bassist Ken Casey backed former City Councillor At-Large Michael Flaherty in the 2009 match-up between Flaherty and Mayor Thomas Menino.

State Rep. Walsh, a Dorchester Democrat, is one of several candidates hoping to succeed Menino after the longtime mayor announced he would not seek a sixth term.
