Pro-choice. That is to say, I believe the choice to bring a fetus to term should be that of the mother. Period. End of sentence. I know it's a cliche, but abortions should be "safe, legal and rare".
I believe we should give women a myriad of tools to avoid having to do it, but I think there are circumstances that, as society, we cannot control, where this most personal decision cannot be usurped by religion, family or law.
Would I do it? I'd like to think "no", but I haven't been raped, I've never been pregnant with a child that will be horribly deformed and probably not survive out of the womb, etc. No man ... and NO WOMAN can say for absolute certainty that they wouldn't do it under the worst of circumstances. It is simply impossible to dictate morality here when you cannot even get a glimmer of the circumstances women making this choice face.
I certainly wouldn't use it as a type of lazy birth control, and I think most women would find the idea of repugnant. I'm sure there will be some women who WILL use it that way, but I think that is acceptable in order to be able to handle all of the nasty cases where abortion really is the lesser of multiple evils.
For those of you who think it could never be the lesser of any evil, CLEARLY your full of it. Consider the case where if you don't abort the baby, Mom dies. Very simple. The baby is going to die anyways. If you are "pro-life", you would abort the baby to save Mom's life.
To those trying to legislate morality of abortions, get off your high horse and join the real world where decisions are complicated, not having enough money to feed your family is a real problem and there are actual consequences in terms of law, poverty and social stress to forcing people to have children they don't want.
