Pack the court like that and see what happens. It would be screamingly obvious to all but the most hardened hater that the democrats were trying to pervert the court, and out you go.Keep in mind as well, that if the democrats pack the court, there will be nothing to stop Republicans from doing the exact same thing.
If we are ever stupid enough to let them get back into power, yeah. There aren't enough stupid white people left to do that, though.
The GOP hasn't won a majority since 2004. They have to use tricks to get any power at all- Gerrymandering, voter suppression, etc.
