Dr. Donald Berwick, the ex-CMS administrator and co-founder of the Institute for Healthcare Improvement, has announced his campaign for governor of Massachusetts.
Berwick, 66, resigned from his CMS post in November 2011. He was followed by Marilyn Tavenner, whom Congress confirmed as Berwick's successor in May.
Berwick took to the Internet with the news, making the announcement on his campaign website and posting it on a separate Twitter account for his campaign. In his statement, he said he'd been mulling the run for months. He first showed interest for the governor's office in January. Democrat Deval Patrick has held the governor's seat since 2007 and announced he would not run for re-election. Republican Charles Baker, who lost to Patrick in 2010, is also considering a campaign.
