State Sen. Daniel A. Wolf, who represents the Cape and Islands on Beacon Hill, announced his candidacy for governor this week.

“With your encouragement and support, with an entrepreneurial spirit and love for our great commonwealth, I’m excited to announce my candidacy to be your next governor,” Mr. Wolf, a Democrat, said in a video posted Wednesday on You Tube and his campaign website.

Dr. Donald M. Berwick, a Chilmark summer resident and former Obama administration official, announced Monday that he will run for governor in 2014.
The pediatrician, former Harvard professor and one-time temporary administrator for the Centers for Medicare and Medicaid Services, spoke on the Vineyard last summer at a forum on health care.
