Trump has already canceled plans for an election night party at his Washington, DC hotel, choosing instead to stay at the White House, a decision made with a serious stink of loser.
In 2008, when Barack Obama was elected president, enthusiastic locals flooded the streets in front of the White House to celebrate. Trump definitely doesn’t want to see that if he loses early. And if it stays too tight to phone with millions of postal ballot papers that haven’t been counted in major swing states and he tries to explain the win as part of a plan to keep counting the ballots likely to go against him, To delegitimize, he would also like to stem the pushback.
Basically, Trump is a scared little man who wants to hide from the people while desperately clinging to power at all costs.
