the democrats are giving lip service to legal language that talks about protecting abortion rights through the end of pregnancy. that's a political loser and lets the republicans off the hook.
the problem with trying to write a law on abortion is there are so many medical contingencies that its almost impossible to do. the democrats have the right idea: that you need to leave open the possibility of an "abortion" for any period of time in the pregnancy because things can go wrong that could kill the mother or leave the baby in a horrible physical state. but when you include such language allowing an abortion at any time for "mental health" reasons for the mother, you leave open a potential parade of horribles that republicans can use as a reason to not vote for it.
i'm not sympathetic to having an abortion at 8 months because of the mental health issues of the mother, but i think that never happens. i am sympathetic to democrats trying to craft a law that is politically acceptable, while also needing to include language that does not foreclose the possibility of a later term abortion if necessary and decriminalizes it. and i am not sympathetic to republicans that refuse to compromise for any reason and make the process that much harder.
