There is no method for the Supreme Court to put a stop to this crap.
Sure there is. Take control of it like they did the Florida election. Decide it falls within their jurisdiction. There are plenty of methods. All it takes if for the Supreme court to quietly get the word to his attorneys to file a motion with them.
It’s corrupt to demand he leave the campaign trail for 8 weeks as the result of a primae facia corrupt political prosecution.
Don’t believe me? Watch how fast the Federal Courts would swarm in with a half a dozen injunctions if a prosecutor in Lubbock decided to open a department store rape case or some such against Biden, Hillary, Hunter, or Schumer. And then that local demanded Biden be there every single day for the next two months.
