Five men have pulled papers to run for the Fourth Suffolk district to replace State Rep. Nick Collins, who is seeking to fill the First Suffolk Senate seat left vacant by Linda Dorcena Forry this year. Democrats Ryan McGoff, former Collins staffer David Biele, former Walsh staffer Daniel Manning, William W. Higgins, Jr., and Matt Rusteika have thrown their hats in the ring so far to represent the district serving South Boston and sections of Dorchester.

Collins is the heavy favorite to win election to the State Senate in a special election set for May 1. He will face unenrolled candidates Althea Garrison and Donald Osgood, Sr. On Tuesday, Collins was endorsed in the contest by Boston City Councillor Andrea Campbell.
