At first, I was in agreement with that.
But now, I disagree. Would they hate Trump any more, or any less, whatever he says? And the traitorous, treacherous scum will break ANY oath they swore to keep Trump out of the White House.
Trump should swear to defend and disband the FBI, and appoint special prosecutors (might take dozens of 'em) to investigate all the vile treason they've been up to. It would even be a good touch to tear down the FBI headquarters building, as a promise to the American people that law enforcement will NEVER be so politicized, ever again.
Back to between now and the election: Trump should quote a line from Winston Churchill: "We will do our best, let them do their worst!"
