If Dems take the House and Senate, they will have the power to determine the jurisdiction of the Supreme Court. They could, for instance, pass a law to prevent them from hearing cases on abortion or the ACA; the Constitution specifically gives them that power. A conservative court can be managed, the important thing is to show up for the midterms. If Dems had shown up in 2014 they could have kept the Senate and saved us all kinds of trouble.
