Unfortunately I dont think Clinton does this without a pretty good belief she is going to win. Trump, besides tweeting has done little in the way of response. He should be getting people ready to hit every county in the three states. He has the funds, both his and the campaign’s. The first thing he must do is ask Clinton if she is retracting her concession. Gore did the morning after. If she says yes, then go to war. Challenge the result in every state she won where the deadline hasnt passed on the grounds of fraud. And the GOP Congress must right now state unequivocally there will be no cooperation with a Clinton administration and investigations into all aspects of the foundation, her tenure at State, even the nonsensense about Pizza will be all the Congress will do.
Sounds like a good plan to me.
