At the end of the day, bills like this are a way to try to end-run around the legalization of abortion and the growing recognition that it is often a medical decision, not a legal or moral one. (And, when it is a moral decision, it may often be correct to decide against the life of the fetus.) Even if it passes, given that the Democrats seem to be waking up and may actually take back the House and Senate, I would expect that we would see more bills piling up to undercut this bill.
The question I have, though, is why Republicans keep bothering. They don't win these sorts of fights. So, the only consequence this will have is to markedly increase suffering in the US. That seems to be pretty much their MO these days -- the more people are hurting, both at home and around the world, the better.
