The garden is planted, the bread is baked, the floor is swept and I have no campaign events until tomorrow morning. So...
First as to upper limits on abortion of healthy fetus. Only 2% of abortions are third trimester. The vast majority of those are either medical emergency of the woman or severe fetal defect. Occasionally it is a drastic life emergency (severe sudden financial crisis, abandonment, homelessness, etc.) A few involve a woman who was raped and is in denial - especially very young girls - until she just can no longer deny she really truly is pregnant. Women just don't sit around for 8 1/2 months and then decide to have an abortion because they have a little headache or can't fit into prom dresses - statements made up by anti-abortion fanatics. Women do sometimes postpone the procedure due to all the laws designed to make getting an abortion as difficult, time consuming, and expensive as possible but that is not the woman's choice. So, if you say you want to outlaw late abortion, well, who decides what is and is not an emergency? Only the woman in consultation with her doctor and others she might choose to bring in. Which will never be a state legislator.
For the record, I was raised in an observant Jewish home although I became a conscious atheist at an early age. The Jewish faith does not prohibit abortion and explicitly does not consider abortion murder. Halacha (Jewish law) holds a human life begins when a baby is born and draws breath. And also if there is a conflict between the needs of the pregnant woman and the fetus, the woman takes precedence, and no woman should be compelled to carry a child against her will. So if you religion teaches otherwise and you want to follow that in your own life, fine, but it violates the First Amendment to make your religion secular law that everyone must follow.
As to putting women in prison to stop them from getting abortions - not so far-fetched. During the civil war in Yugoslavia thousands of Croatian and Bosnian women and young girls were held in rape camps which are exactly what they sound like, repeatedly raped by Serbian forces. During the entire time abortion was legal up through the first six months of pregnancy, so women who became pregnant were held prisoner until the seventh month to prevent abortion.
I know of two cases in this country. In one a college student, who like many students was having a hard time financially, got involved in a white collar crime. She was extremely remorseful, very anxious her family not hear since she said she came from a traditional Chinese-American family where the disgrace of one was the disgrace of all, it was a first offense. Her co-defendants all got probation and community service. But the judge learned she was pregnant and had already made an appointment for an abortion, so she was sentenced to prison explicitly to prevent her from getting an abortion. Her lawyer challenged this, successfully, but the judge knew the order wasn't legal. All that was necessary was to hold the woman for a few months until she could no longer get a legal abortion. The woman dropped out of school and is now a struggling single mother who feels she let her family down.
The other case was a teen. She was uncertain what she wanted to do, and she and her parents had scheduled a consultation with a doctor to learn about abortion. She wanted information so she could make the best decision for herself. Her boyfriend and his parents showed up armed at her home and held the family hostage. They called police, but were unaware the boyfriend's parents had made an arrangement with the local police chief, an anti-abortion fanatic. He arrived and arrested the parents for "endangering the welfare of a minor" by taking her to discuss abortion. She was put into foster care. Again, the charges did not have to legally stick and did not, all that was necessary was to keep the young woman in custody of the state until she was too far along to get an abortion.
Yes, we all have our opinions. If you have an opinion that abortion is bad and therefore choose not to have an abortion I respect that even if the circumstances were ones where I myself would never carry a pregnancy. I oppose the one child policy and forced abortions that took place in China. But - when you try to make your opinions into law, so that my body is governed by your opinion, I am going to object to my dying breath and beyond.
