“It depends on if Schumer needs their vote, because he’s done very well keeping the big family together, but assuming Republicans don’t bolt, I think I’ll go with three Democrats going the other way," Miringoff, director of the Marist Institute for Public Opinion, told Hill.TV's Joe Concha on "What America's Thinking."

Schumer has personally come out strong against Kavanaugh, saying he will oppose him “with everything I’ve got.”

The New York Democrat has cited the future of the Affordable Care Act (ACA) and Roe v. Wade, which legalized abortion nationwide, among his reasons for opposing Kavanaugh. 

“On these two issues when he campaigned, President Trump said he would only appoint pro-life judges, he wanted to send Roe back to the states, that means repeal,” Schumer said earlier this month. 

“So when you put those things together, Trump with what he said he was going to do and the vetting of this list, this nominee will repeal Roe and women’s reproductive freedom and repeal ACA far against what the American people want."
