State Rep. Nick Collins easily won the Democratic nomination to replace Linda Dorcena Forry as the next state senator in the First Suffolk district on Tuesday. According to unofficial elections results, Collins amassed 3,722 votes— or 94.59 percent of the vote— as the only printed name on the ballot.

Collins will face off against two unenrolled candidates— Althea Garrison and Donald Osgood, Sr. in a May 1 final election.

It was a low-turnout day, with only 3.68 percent of the district’s 111,183 registered voters turning out to cast 4,096 cards. The 213 write-ins counted for 5.41 percent of the vote in Tuesday's election.

Forry left the Senate seat vacant when she resigned from office in January to accept an executive position with Suffolk, the Roxbury-based construction firm. Forry endorsed Collins to succeed her last month, joining state Rep. Dan Hunt, Rep. Dan Cullinane and Suffolk County Sheriff Steven Tompkins in supporting Collins’ candidacy.

Collins has some $160,000 in his campaign account and is the heavy favorite to win in May to complete Forry’s term. He will need to run for re-election to the seat this fall and is likely to face competition from several people who have secured nomination papers to run in the September primary, including Osgood, Duckens Petit-Maitre (D), and unenrolled candidates Garrison, Jesus Rosa, and Elciana M. Ogunjobi.  Candidates for all state and district races have until May 1 to file nomination papers.
