I think people placing their hopes in the courts have a misunderstanding of what happened in Bush v. Gore and buy the Democrats' story that the Supreme Court elected Bush. No courts were ever going to go so far as to overturn the result of an state's election. It was always going to require the intervention of state legislatures.
State legislatures with Republican majorities should ensure that all of the electors from their state are diehard pissed off Trump supporters.
