No, a portion of their actual election fraud plans were completely successful, in the weeks leading up to the election the stacked courts allowed GOP states to purge voter rolls with no notice to those that were removed, and after registration deadlines. It's only "legal" because the court said it was, because they're supposed to be the oversight to prevent fraud and abuse.

There is nothing to actually stop the courts from claiming something clearly illegal and in direct contradiction to the law as written is just fine. It would appeal up to the Supreme Court, whose decision is final, period. The only response would be for Congress to Impeach them and a new court to revisit the case. And that'll never happen with our extremely partisan Congress.

This is why the Republicans have focused on the Judicial for over 50 years. They realized that it's the only part of the government that actually has power to override anything else single-handedly. Just get a small majority in Congress (not even if you get the opposing side fragmented a bit) and the Sourts can do whatever the fuck they want with no resistance.
