Treasurer Steven Grossman has adjusted his thinking on a potential 2014 gubernatorial bid to say he is “leaning strongly in that direction,” though with an attention-grabbing U.S. Senate race on the horizon he said he has not yet made up his mind.

“I haven’t made a decision yet, but I’m leaning strongly in that direction, meaning strongly in the direction of running for governor, and let me tell you why,” Grossman said on WCVB Channel 5’s “On the Record,” which aired Sunday morning.

“Governor’s the chief executive of the state," he said. "We all know that. It’s a role I’m very comfortable playing. I played it in business for many years, non-profit organizations, last two years at Treasury. What the governor does is the governor lays out a set of priorities, a vision for the future of the Commonwealth, common sense solution, executes, pulls the team together and is held accountable by the people of the Commonwealth. That’s a role I’m comfortable playing, so I’m leaning strongly in that direction, and I think that’s the best I can tell you at the moment.”

The only other potential candidate to publicly state an interest in a possible run for the Corner Office is Lt. Gov. Tim Murray, who said he was thinking about it in September, and then in November told a Greater Boston Chamber of Commerce audience, “Like many of you in the room, I would like to be governor. I think it's okay to say that out loud.”

In late October, Grossman told the News Service he would start thinking about a run after the November election, and said, "I consider myself to be a fairly decisive person." Murray’s potential candidacy appears to have not deterred Grossman, though the treasurer and former Democratic National Committee chairman said he's focused on a looming special election for U.S. Senate.

Pressed to make an announcement, Grossman said, “Leaning strongly in that direction, I think gives people an indication of my thinking. We’ve got a special Senate election coming up imminently; I want to play an important role in that because I want to make sure a Democrat succeeds John Kerry.”

Grossman said he had a “good December” for fundraising, and said that the strength for any candidate would be in a grassroots organization.

“It is all about relationships at the end of the day," he said. "In this Commonwealth, as you well know, it is all about the grassroots. You saw how Elizabeth Warren did so well? It was because grass roots welled up, and that’s how the Senate race is going to go as well.”
