Abortion supporters at Women's March in Boston turn out in droves to support Harris presidency

"How many of you are going to vote on Tuesday? How many of you can't wait to wake up to a woman president?" Rev. Dr. Deborah Haffner, of First Unitarian Universalist Society in Newton, Massachusetts, asked.

"Today's message is that we want everybody to vote," Murphy said.

Abortion has remained a hot-button issue in the 2024 election - with abortion being a top issue for many female voters.

Fifty-nine percent think abortion should be legal in all or most cases, up from the previous high of 57% in September 2022 and a record low of 44% in April 2022. 

Overall, just 7% think abortion should never be permitted, while five times as many say it always should be (35%). Another one-third (32%) say abortion should be illegal except in cases of rape, incest, or to save the life of the mother. 

Former President Trump has shifted his stance on abortion during the election cycle, with the Republican nominee hoping to attract independents and some disillusioned Democrats, but running the risk of alienating his pro-life base.

Throughout Vice President Kamala Harris' campaign, she has argued that Trump - who nominated three conservative justices to the Supreme Court who later voted to overturn Roe v. Wade - is responsible for worsening medical care for women and that he would seek further restrictions.

Harris has cast her position on the topic as creating legislation to restore the national abortion right that was eliminated following Roe v. Wade.
