"We must eliminate business regulations which serve no legitimate public purpose but hamper capital investment and economic growth," Bachrach said. "It is our overregulation which shows growth and prevents new companies from moving in."

Bachrach also chided Weld for letting the state's infrastructure fall into disrepair.

"We will rebuild the roads, bridges and ports which this administration has let fall apart, so commerce can flow and new companies can grow," he said.

Bachrach said that, unlike Roosevelt and Barrett, he is "not timid about supporting a progressive, graduated income tax." Such a tax would make people with higher incomes pay a higher tax rate.

"This is the most helpful tax relief package that working and middle class citizens have ever seen," Bachrach said. "Under the proposed plan, 92 percent of our citizens will get a tax break."

Bachrach said he would change the welfare system by offering job training and day care to the poor.

"We will not join those who attack the poor through punitive measures," Bachrach said. "But rather, we will engage in new job creation in partnership with the private sector."

Bachrach heavily stressed yesterday the differences between himself, Weld and his fellow Democratic challengers.

"On important issues such as crime, welfare reform, economic development, education and other critical matters, I will offer my own package in stark contrast with both this Republican governor, as well as the Democratic legislators running for governor," Bachrach said.

Hecklers twice disrupted Bachrach's speech yesterday. On one occasion, an elderly woman yelled at Bachrach for his pro-choice stand on abortion.

And at the conclusion of his speech, a man in the audience screamed, You're just another Dukakis."

Bachrach's announcement here in Boston was part of a busy day of campaiging for the former state senator.

Bachrach also gave speeches to kick off his candidacy in Pittsfield, Springfield, Worcester and Fall River.
