You don't have to be far left to have been against that bill. It was prohibiting a particular, and very seldom used medical procedure. The name "partial birth" was tacked onto it to make it sound particularly heinous, but it's no worse than other late-term procedures.

The main reasons to be against that bill were: it contained no exception for the health or even life of the mother; it takes the decision of the particular method out of the hands of the mother and her doctor; it is a very rare procedure, only used when other methods are inappropriate.

That ban will not prevent a single abortion.
