The courts have largely been rejecting Trump’s lawsuits.
His two wins were letting observers get a little closer and justice Alito reinforcing Pennsylvania to do something they were already doing.
The Supreme Court is very unlikely to weigh in on this. They don’t want to be seen as partisan hacks. The best case scenario for Trump is that votes received after Election Day won’t be allowed to be counted, which won’t make a difference.
Reports are now that Trump is privately beginning to understand that he has truly lost the election. He plans to let the lawsuits play out and will then concede, in his own Trumpy way, I’m sure.
