NEW MILFORD — After nearly three years at the helm of the town’s Democratic Town Committee, Andy Grossman stepped down Tuesday.

“To do the job right, in a very competitive and challenging political environment, the chairman, in my opinion, needs to devote considerable amounts of time,” Grossman said in a statement released Wednesday. “I no longer have the luxury of committing enough time to do the job justice.”

Grossman, who lead the committee of about 30 members during a Democratic resurgence in municipal government, will be missed as the head of the group but will stay very involved, said Pete Mullen, who is taking over as chairman.

“During Andy’s tenure, we won the mayor’s seat, we took a majority control on the Town Council, and we took a majority on the Board of Education,” Mullen said. “We picked up a seat everywhere.”

Grossman’s tenure ends after the Democratic Party had a rough local showing in the presidential and state legislative elections earlier this month, and experienced some division within the party over the proposed construction of a power plant on the old Century Brass site.

Mullen said the surprise election of President-elect Donald Trump, and the power plant fight, which pitted Mayor David Gronbach against some members of his own party, had nothing to do with Mr. Grossman’s resignation. Grossman, in an interview, said he had been considering stepping down since September, but decided to remain on until after the election.

“It’s politics,” Mullen said. “We had our U.S. senator win and our congresswomen win, but Donald Trump had an effect on this town that went down the line.”

Democratic 5th District U.S. Rep Elizabeth Esty and U.S. Sen. Richard Blumenthal both kept their seats. But locally, Republicans retained control with wins in the open 67th District state representative race and 30th District State Senate race. Trump won New Milford in the race for president.

Grossman said he thinks the party will be strong in years to come.

“Since the election, we’ve had unprecedented numbers of people looking into getting involved.” Grossman said.

He expects Democrats to retain control in local elections in a year, and thinks the party will put forward strong legislative candidates in two years.

Mullen, a former member of the Town Council, said he thinks Democrats will continue to change the political landscape of the previously Republican-dominated town.

The Republican Town Committee is also under somewhat new leadership: It elected Mike Barnes to replace Town Council Member Pete Bass as chairman last March.; 203-731-3411; @bglytton
