Donald Berwick, who formerly ran Medicare for President Obama, formed a fundraising committee on Tuesday, a further indication that he may run for governor in Massachusetts in 2014.

“I’m getting more and more serious,” he said Tuesday night.

Berwick’s interest in the position came as something of a surprise when it surfaced publicly two weeks ago, given his lack of experience in electoral politics.

But Berwick, 66, said he has been increasingly serious about a run, meeting with influential Democrats around the state since the fall. He said Tuesday that he opened the campaign account so that he could begin raising money—which would allow him to further test the waters.

“I haven’t made a final decision,” he said. “ ’Seriously considering’ is still the right way to put it.”

Berwick said he has not set a timeline for making a final decision. But he continues to sound like a candidate as he talks about “getting more and more excited about what I’m learning” while meeting with people around the state.

He said he is lining up volunteers for a potential campaign and meeting with professionals who may ultimately become his campaign staff.

Obama named Berwick to run the Centers for Medicare & Medicaid Services in 2010 as a recess appointment. He left the administration in late 2011, after Republicans signaled they would attempt to block his confirmation.

On Friday, Lieutenant Governor Timothy P. Murray said he would not seek the Democratic nomination in 2014, further opening the field. State Treasurer Steve Grossman is also considering a run on the Democratic side. In addition, Charles D. Baker, a Republican who ran in 2010, may get into the race for governor.
