Bay State Sen. Elizabeth Warren stepped up her attack on Donald Trump last night, calling him a “racist bully” — and saying that a vote for Green Party candidate Jill Stein is effectively one for the Republican nominee.

“Donald Trump is a thin-skinned, racist bully and he has proven that day after day, week after week, month after month for more than a year,” Warren said last night after a speech at Roxbury Community College, adding later: “He has made hate part of his campaign, and I think there comes a time when you just have to call him out on it. We have to say we are a better country than that.”

When asked what she would say to far-left voters who would consider voting for Stein over Democratic nominee Hillary Clinton, Warren sought to warn them off.

“Anything you do that helps Donald Trump get one inch closer to the White House is a danger to all of us,” Warren said, adding that a vote for Stein “moves Donald Trump closer to the White House.”

Warren, who touted her agenda for boosting the middle class by closing corporate loopholes, declined to directly address whether she would support the charter school ballot question.

She did, however, say she would consider supporting the legalization of marijuana in Massachusetts so long as regulations are in place.

“I would be open to it because I think the problem we have right now in Massachusetts is that we decriminalized. There is marijuana available, but there is no regulation,” Warren said. “I think we should learn from the other states that have already done this.”

The Cambridge Democrat declined to address recent comments by former Red Sox pitcher Curt Schilling, who indicated during radio interviews last week that he was mulling a run against her. She said her concern is working for the people of Massachusetts and “trying to make sure that Donald Trump never gets any place near the White House.”

When asked point-blank whether she had any concerns about Schilling running against her, Warren said: “No.”

She was also asked about recent pay-to-play allegations brought against the Clinton Foundation.

“I don’t know any more than what I read in the papers,” she said, “but she (Clinton) says the data doesn’t add up and that the pieces are not there.”
