Cam Charbonnier, who withdrew from the race for state representative in the 12th Suffolk district earlier in July, today endorsed one of his former rivals for the seat. Charbonnier threw his support to Stephanie Everett, one of three remaining Democrats who will appear on the Sept. 1 primary ballot.

"Having known Stephanie for several years and watching her throughout this race I have no doubt she is the right candidate to represent the 12th Suffolk District," Charbonnier said in a statement from his campaign. "Listening to her in campaign forum after forum, seeing her tireless commitment during years of community service, knowing her personal story, and the work she has done during her career in state government, I know that Stephanie will be a State Representative that fights for the entire district with a unifying voice and dogged determination that benefits all residents.”

The endorsement is the latest boost for Everett, who won the support of the Ward 17 Democratic committee in a unanimous vote last week.

“Cam is a good man who works hard and cares deeply about his community,” Everett said. “He added so much to this race as a candidate; I am grateful for his voice and his support,” she said.

The other two candidates in the race are Jovan Lacet and Brandy Fluker-Oakley, both attorneys from Mattapan. Fluker-Oakley has been backed by the Boston Teachers Union and Rep. Chyna Tyler.

The contest between the three Democrats on Sept. 1 will choose a successor for Rep. Dan Cullinane, who decided not to seek re-election this year. The district includes parts of Mattapan, Dorchester, Hyde Park and Milton.
