State Rep. Linda Dorcena Forry endorsed Sonia Chang-Diaz in her general election matchup against state Sen. Dianne Wilkerson on Thursday.

Forry, a Dorchester Democrat, backed Wilkerson in the Democratic primary and said earlier this month that she was inclined to stay neutral as Wilkerson launched a write-in campaign for the general election after losing in the primary.

In a statement, Forry remarked on her relationship with Wilkerson.

"I endorsed Sen. Dianne Wilkerson in the primary election, as I have in the past, because I have great respect for her record of service and achievement in the Massachusetts state Senate," Forry said. "I continue to admire Sen. Wilkerson for her legislative record and for her courageous stands on issues that I care about. I will always consider her a friend and a colleague."

But, ultimately, Forry said she is supporting Chang-Diaz, the Democratic nominee.

"On Sept. 16, the voters in the Democratic primary made their choice and a recount of the votes confirmed the result: Sonia Chang-Diaz is the nominee of the Democratic Party," Forry said. "I now endorse her candidacy in the Nov. 4th election."

With her endorsement, Forry became the third member of the Massachusetts House of Representatives that endorsed Wilkerson in the primary but is now backing Chang-Diaz in the general, joining House Speaker Salvatore DiMasi (D-Boston) and state Rep. Byron Rushing (D-Boston). For PolitickerMA.com's up-to-date tally of who Wilkerson's primary backers are supporting in the general, click here.
