Then, according to that source, you are correct. I do not agree with Bernie if that is his full position. There is a point when life should be protected, however that does not cover all cases. Meaning, if there is a significant medical reasoning for needing a late term abortion.
Hillary gave the exact correct answer in that case, though, by mentioning that Roe v. Wade (and not mentioning Casey v. Planned Parenthood) has already established the laws for late-term abortions.
