BOSTON—Robert Reich, former President Bill Clinton’s first secretary of labor, announced today that he will be seeking the Democratic nomination for Massachusetts governor on a platform of improving the economy.

In an interview after the announcement, Reich said that a November visit to a Harvard class was a “catalyst” for his decision to run.

Reich said that the discussion he had with the class, Religion 1529: “Personal Choice and Global Transformation,” about personal courage was a “profound moment” for him, and that later that day he began to explore a run for governor.

“I left that class thinking to myself—this state is a mess and I need to run for governor,” Reich said. “It was from that moment that I began to think I’ve talked the talk a lot, now it’s time to walk the walk.”

Reich, a 55-year-old man who stands 4’10 1/2” tall, was frequently self-deprecating in his speech, which he gave to a crowd peppered with Harvard professors and students.

Reich started out with a joke, as he pulled out a wooden step to stand on.

“At least I stand firm on my platform,” Reich quipped.

But Reich quickly got down to business.

“I became secretary of labor to fight for the working women and working men of America,” Reich said. “I was a member of an administration that oversaw the longest economic expansion and new growth in history. We added millions of new jobs.”

Reich contended that there is a “vacuum of leadership” at the state level, particularly when it comes to the economy, and said that in his campaign he would be “focusing like a laser beam on the economy and on jobs.”

There are “two Massachusetts”—the haves and the have-nots—said Reich, currently a Brandeis University economics professor. He plans to present his economic plan tomorrow in Lawrence, Mass., a city known for its bleak economy.

Reich said that he did not think it would be easy for him to win enough delegates to qualify for the September primary, but that he was determined to fight. Reich needs to garner 15 percent of the delegates at the Democratic state convention in June to make it on to the ballot—but many delegates are expected to commit to candidates by the party’s caucus in just over three weeks. Reich joins a crowded field of six Democratic candidates, including likely frontrunners state Senate President Thomas F. Birmingham ’72 and former national party chair Steve Grossman.

“I have a confession—I am not a big man,” Reich said. “But as the saying goes, it’s not the size of the dog in the fight, it’s the size of the fight in the dog.”

While some critics have said that having Reich in the governor’s seat would mean higher taxes, Reich vowed to do “everything in my power” not to raise taxes.

“I am not going to give you this ‘read my lips’ or ‘over my dead body’—that’s irresponsible,” Reich said. “How can we ask people to pay more taxes when everyone knows there’s so much waste in state government?”
