State assistance to help communities combat the effects of climate change is a key tenet of his re-election platform, Gov. Charlie Baker said.

Charlie Baker’s resume includes stints as former CEO of Harvard Pilgrim Health Care and state secretary of finance and administration. But visiting the Vineyard this weekend, the Republican candidate for governor told the Gazette he learned important political lessons as a selectman in Swampscott.

Massachusetts Attorney General Martha Coakley and former federal health care executive Dr. Donald Berwick both won the backing of enough delegates, along with state Treasurer Steve Grossman, to set up a three-way primary race in September. The Democratic convention was held Saturday in Worcester.

The former director of the Center for Medicare and Medicaid under President Obama and part time Chilmark resident addressed a gathering of about 25 people in West Tisbury Saturday morning.

Attorney General Martha Coakley, addressing a meeting of Martha’s Vineyard Democrats Saturday morning, said she feels confident about her chances to be elected the next governor.

Granted an extension to respond to a state ethics commission decision, gubernatorial candidate and Cape and Islands State Sen. Dan Wolf will now remain in office until at least Sept. 19.

Mr. Wolf announced last Thursday that he would resign his seat on August 29 and suspend his campaign for governor because of an ethics commission decision that his partial ownership of Cape Air created a conflict of interest.

In a statement on Wednesday this week, Mr. Wolf announced that he was granted an extension and will present a petition to the ethics commission next month.

State Sen. Dan Wolf announced Thursday that he has suspended his campaign for governor and will resign his state Senate seat next week in the wake of a state ethics commission ruling about his ownership of Cape Air.

More than 30 years ago Dr. Donald Berwick began seeing patients in the Martha’s Vineyard Hospital emergency room. At the time, the ER was staffed by visiting physicians on weekends, so he helped set up the schedule and find the doctors a place to stay for the night. Since then, he has stopped seeing patients, was temporarily appointed by President Obama as administrator of the Centers for Medicare and Medicaid Services in Washington, D.C., and in June, declared his campaign for governor of Massachusetts.

In a standoff with the state ethics commission, state senator and gubernatorial candidate Dan Wolf is publicly disputing a commission opinion that his role as owner of Cape Air is a conflict of interest. The ethics commission is standing behind its opinion and strongly refuted a statement posted by Senator Wolf online this week.

Mr. Wolf, a Democrat, represents the Cape and Islands in the state senate. He founded Cape Air 25 years ago and now has a 23 per cent stake in the company.
