It's too soon. They want to force us to attack before we are ready. We need one more before we go after Roe, because if we go after Roe and fail, the next judicial appointment will literally be a referendum on Roe with no pretense.
Who says the best initial strategy is to overturn Roe. Perhaps chipping away at it bit by bit, incrementally, is the path they will choose. I would predict just that. Eventually I believe it will be overturned, but until then the court may just take little bites, until the time is right is finally kill it off entirely.
