I'm not convinced that a revisit of Roe vs Wade will end in the same outcome. People are starting to understand that life begins at inception. Those that don't, are soon going to realize that if fetuses can survive outside of the womb sub 20 weeks, then killing them off right up to that is wrong.
I believe 22 weeks is doable now. I look for that to decrease in upcoming years.
If I'm not mistaken, the court already agreed to review something related to Roe Vs Wade recently. Perhaps someone else can remind us what that was, unless I am mistaken.
