He’s toast if it’s true. I’m not sure if anyone wants to hear fighting from someone who used aborted baby body parts in medical research.
This is just a sign, sadly, that his team was not prepared. He just may not be ready for the major leagues of politics yet.
The most effective witnesses for the goodness of Christ's grace seems to be those who sank as far into sin as possible. The guy who never really strayed from the path, whose sins never caused major repercussions to his life, doesn't get near the press as the former convict who killed a man and ran a drug empire talking about how God delivered him.
Likewise, a neurosurgeon who worked with fetal tissue 20+ years ago is the most compelling voice of how he came to realize that abortion is an abomination that is unnecessary for medical research.
He (and by that I mean both himself and his team) should have anticipated this and prepared a response beforehand.
Not all fetal tissue research comes from abortions. Some of it comes from miscarriages. When he did his research, he may not have realized which source it came from, only the gestational ages.
Depends on whether it was induced vs. spontaneous (e.g. stillborn or similar).
