The draft Supreme Court decision overturning Roe v. Wade was leaked in an effort to energize liberal voters ahead of the midterms, a former pollster and adviser to President Bill Clinton and Hillary Clinton told Fox News.

The draft decision, written by Justice Samuel Alito, said the states should have the authority to regulate abortion since nothing in the Constitution supports it as a right.

“The leak of the … potential Supreme Court decision was, I think, clearly designed to affect both the court, and I think perhaps the midterms,” Harris Poll chairman and Stagwell CEO Mark Penn told Fox News. “I think that Democrats were rather lackluster going into these midterms, had kind of a feeling of growing defeat coming.”

“This is going to provide an ability for Democrats to energize their base somewhat more than was going to happen without this,” Penn added. “I think that that breathed new life into Democratic hopes for those midterm elections.”

Demonstrators gathered outside the Supreme Court soon after Politico published the draft decision Monday night and remained until after midnight. Hundreds on either side of the abortion debate assembled again on Tuesday.
