Any individual is capable of any evil thing, and many do not abide by their professed principles. That's just how it is.
But you have to go with the declared statement of a group or party. I don't know what would happen if the GOP dropped the pro-life plank; I'd probably vote for them because I think they're better on security and don't want to control my every waking moment, but my big moral commitment would be gone. That said, there's no Dem I have seen that I would vote for on any grounds.
If the Republicans drop the pro-life plank, I probably won't vote any more, and the Republicans are in big trouble come next election.
The sad thing is there is a local story I was just reading very similar but with profound differences, and the judge gave the parents guardianship rather than the husband. Whether he can appeal or not, I don't know.
