From what i can find that puts it at about 5 months. Many have used 20 weeks as their standard for the cutoff. I don't find this entirely unreasonable as a compromise point IN A DEMOCRACY. I would personally make it about 10 weeks if I were king-for-a-day(henceforth known as KFAD) but given that we are in a democracy and there are many, many people that would like it to be much later than 20 weeks, I think a 20 week ban would be acceptable by most. If the GOP doesn't adopt a strategy of on compromise on this, it is going to lose us many elections. and when we lose those elections we are going to lose the ability to hold sway on much more than just abortion. I have a preference on abortion, but I'm not willing to let abortion be the sword that the party and the rest of our conservative issues dies on.
It is a compromise position. I am not in favor of a total ban and I was not thrilled with the six week law formerly in Texas. It was workable if a woman would immediately begin her testing after unprotected sex (however many days it takes for a pregnancy to show up). But it left very little room for error.
We don't need more children being born. The idea that everyone is going to start practicing safe sex is not credible to me. It's going to happen. It's unfortunate but that's the reality.
