No, it won't work. But, they will have their talking points. "These rulings are not legitimate...the evil republicans kept our judges off the court." And likely they will try to push for what the court would have ruled if it had been packed with marxists.
The problem with ‘pushing’ for the result they want is in the codification of the statute that implements that ‘want.’
For instance, abortion has been deemed a STATES prerogative to govern and not a Federal right or issue. If the federal Congress and Administration implements a statute trying to end-around that, even if it is a ‘law,’ it is still Unconstitutional by USSC edict and would have to pass the Roe v Wade overturning ruling by the USSC. It would really have to be some kind of tricky/snarky backdoor way of implementing abortion without actually directly making it a ‘right.’ But, they will try it.
