Bottom line: if it goes back to the states, it's likely that none of them would ban it because places like google, amazon, twitter, airlines, sport franchises, etc would all cease operations and shut those states down until they comply the wishes of the dear leader in DC.
The federal government is going to keep needing geeks near me in Huntsville for DOD R&D on planes and missiles and missile defense. Same with building boats in Mobile, AL. Same with all the cargo coming into the deeply drudged beaches of Mobile so it can be carried up into the heartland. Same with all the car manufacturers spread out across Alabama with low cost-of-living labor in Alabama and our right-to-work ease of employment. Same with people buying our cotton, peaches, peanuts, chicken, pork, and tons of other agriculture. The same with all the tech companies growing in Huntsville, AL and Birmingham, AL because they need computer geeks more focused on data structures and algorithms instead of MIT or Google "scientists" stuck on trying to figure out differences between men and women.
Basically, the liberals need us more than we need them and some of us red-staters know it and aren't bending over backwards trying to claim God's rainbow quit meaning God keeps His word and now means the best sex is the kind that tears up your butthole.
Joe Biden will immediately pack the court. Susan Collins and Murkowski vote yes to add four new Supreme Court Justices despite Joe Manchin voting no. So that's 51-49 in favor of packing the court and then they will vote to reaffirm Roe vs Wade as the law of the land. John Roberts is probably warning Kavanuagh, Gorsuch and ACB to leave Roe vs Wade alone. So my suspicion is that it is what they are doing. Even though they probably think that it should return to the states but due to political considerations, it is simply not possible at this moment. Maybe not the next 50 years. Or 100 years.
