Playing politics and attacking the court’s credibility seems dangerous. If I was a justice on the fence this may be what pushes me the other way (I admit I’d be a lousy justice since something like this could affect me).
The bigger deal is if I were 1 of 4 justices on the losing side of a 5-4 decision. If the court’s credibility is being attacked by congress, I’d feel the need to side with the majority so that it isn’t a 5-4 decision. Maybe the Democrats are expecting a 5-4 their way and hoping to turn it into a 6-3. I doubt they are thinking that much though and are just making threats.
