I can say this much though. While Roe v Wade (which isn’t even 100% responsible for the legalization of abortion) and Obergefell v Hodges won’t be overturned, the following will potentially happen as long as conservatives get the 6-3 majority:
1. The Judicial Branch will act less like the Legislative Branch and more like what they were originally envisioned by the Founding Fathers. This is what bothers the Democrats the most. The fact that they will appeal to the Constitution more than their issues and stay neutral will make it harder for them to enforce or pass their laws. This is why they are wanting to pack the court.
2. While Democrats have won the battle of legalizing abortion and same-sex marriage nationally, they will continue to lose when womens’ issues and LGBT issues start infringing upon others’ rights. Remember the Hobby Lobby ruling? Remember the Masterpiece Cakeshop ruling? Remember the Chick-fil-A law Texas passed in response to San Antonio’s ban on it in airports? There’s going to be more cases like this where either the conservatives win or the court will narrowly rule. This way, women and LGBT people can keep the rights they were fighting for, but they can’t infringe upon others’ rights to fulfill their social needs.
3. Obamacare (yes, I still keep calling it Obamacare) will be overturned, and chances are, they may rule that the government cannot control healthcare at a national level like it was done in Canada and UK.
4. They’ll continue limiting the government size, hand states rights’ issues to the states while keeping stuff that don’t belong in politics out of politics.
All of these outcomes will bother the Democrats since they can’t have everything go their way anymore, but the constitution will be restored.
