Boston correspondent Ross Kerber interviewed mutual fund industry veteran Robert Pozen and they talked politics.

Pozen says he’s not running so far for the Senate seat from Massachusetts once held by the late Edward Kennedy. But he does appear to be positioning himself as a possible centrist candidate for Democrats mulling how to defeat Republican Senator Scott Brown in next year’s election. USA/

“I’m not running for Senate unless the Democratic Party asks me to, if they want someone who is socially liberal and fiscally disciplined,” Pozen told us in an interview at his office at MFS Investment Management, the Boston fund company where he is now Chairman Emeritus.

If, however, the party wants a more confrontational figure to take on Brown next year, “then they shouldn’t choose me because I won’t be that type of candidate,” said Pozen, a former vice chairman of Fidelity Investments.

Much of the speculation about potential Democratic rivals for Brown has so far centered on possible candidates like Democratic Congressman Michael Capuano and  Alan Khazei, co-founder of the City Year public service organization for young adults.
