I know she has 7 kids which is a good sign on some fronts but Roe v. Wade isn't going anywhere. OTOH, very likely that immigration WILL come before the court...And we know how that is being spun and which half of the population is feeling very emotional about the situation.
All that aside, I'd much rather that a better known quantity be the pick.
Roe will be overturned, probably in my lifetime (I'm entering my mid 60s). All that will do is send the issue back to the states, each of which over time will set up varying levels of restrictions on abortion, all of which will mean very little because those who want abortions will cross state lines to obtain them.
It will take a Third Great Awakening to lower significantly the number of abortions in the US, and I wouldn't put it past the Triune God to initiate one.
