She expressed bitterness that liberals and feminists did not believe her or the other accusers at the time. “They’re hypocrites,” she said. “They worship at the altar of all things Clinton. They’re all over Roy Moore, but they had nothing to say about Bill Clinton when he was accused of doing what he was accused of doing.”

Paula Jones, another accuser, said they were not taken seriously until now. “It’s like me and Juanita and Kathleen have been screaming for years for someone to pay attention to us on the liberal side, and it’s like no one would hear us,” she said by telephone. “They made fun of me. They didn’t believe me. They said I was making it up.”

Mr. Clinton’s behavior, proved or otherwise, has long been an uncomfortable subject for Democrats. Many chose to defend him for his White House trysts with Ms. Lewinsky because, despite the power differential between a president and a former intern, she was a willing partner. To this day, Ms. Lewinsky rejects the idea that she was a victim because of the affair; “any ‘abuse’ came in the aftermath” when the political system took over, as she wrote in 2014.

Ms. Willey, Ms. Broaddrick and Ms. Jones, however, described unwilling encounters. Ms. Jones asserted that Mr. Clinton, while he was governor of Arkansas and she was a state employee, summoned her to a hotel room, dropped his pants and requested oral sex. Ms. Willey, a former White House volunteer, accused him of kissing and groping her in the Oval Office. Ms. Broaddrick, an Arkansas nursing home owner, alleged that Mr. Clinton forced her to have sex during a meeting on the campaign trail in 1978.

Mr. Clinton’s lawyers have disputed all three charges, although he eventually paid $850,000 to settle a sexual harassment lawsuit by Ms. Jones without admitting wrongdoing, citing the political costs of continuing to fight it. None of those cases was part of the impeachment articles against Mr. Clinton, which rested on whether he lied under oath about his interactions with Ms. Lewinsky and coaxed her to lie, too. The House impeached him along party lines in December 1998, but the Senate acquitted him two months later.

Many Democrats condemned Mr. Clinton at the time, but they opposed his removal from office, citing what they considered the partisan nature of the attempt. The fact that some of his accusers willingly collaborated with Mr. Clinton’s conservative opponents troubled some. Others seized on inconsistencies in the women’s accounts. Ms. Broaddrick, for instance, initially denied that anything happened, saying later that she did so because she did not want to be dragged into the political arena. Ms. Willey later said she suspected the Clintons were somehow involved in the death of her husband, which was called a suicide.

Gloria Steinem, who at the time wrote a column generally defending Mr. Clinton, remains unmoved by time. “Most important is to listen to the women themselves,” she said in an email forwarded by her office on Wednesday. “Please watch Monica Lewinsky’s TED talk. It is important, moving and tells you who the abusers are.” She did not respond to questions about Ms. Broaddrick or the others.
