And keeping abortion safe and legal doesn't just mean upholding Roe v. Wade. It means fighting all attempts to limit a woman's right to choose.
The Hyde Amendement, which restricts federal Medicaid funds for abortions and basically ensures that only the rich can have safe, legal abortions, absolutely must be overturned.
We must oppose efforts to ban dialation and extraction or D&X (so-called "partial birth") abortions: the language of any bill that bans these abortions can be read to ban all abortions. Also, D&X's are rarely performed at all, when they are performed in the third trimester it is only in the case of a medical emergency (generally due to fetal death or serious fetal problems, such as the fetus lacking a brain). D&X is safer than induced labor to expell a dead fetus, and it is much medically safer for a woman than actually delivering a dead baby. In a D&X, the fetus is extracted intact, so the family has a chance to say goodbye. (all of that info came from the wonderful Our Bodies, Ourselves by the Boston Women's Health Book Collective).
We must have a comprehensive national healthcare and welfare system, along with a national childcare system and confidential rehab, so that no woman should be forced to have an abortion because she can't afford a child or because if she goes to rehab she'll go to jail. Abortion is not a solution to poverty -- any policy that encourages abortions for poor women is eugenic in nature. The only solution to poverty is the complete abolition of capitalism. Until then, we must make the lives of every woman as comfortable as possible by providing them with the means to live.
