No, both Gore and Clinton did concede and the peaceful transfer of power, which had gone seamlessly since Washington retired from office, not trying to be a king, having the first peaceful transfer of power to John Adams.
And here we are today, in 2020, when an incumbent President who lost BOTH the popular vote AND the Electoral College by a landslide, and along with his Republican enablers, (fact, as few Republican lawmakers have spoken up to defend the election results), still thinks he won ( fact, in his own statements), refuses to concede, and refuses to assist in the transition to the next Presidency, refusing access to the information the next Presidents needs, thus hobbling the next President, the republic itself, and the American people. NO other American President in nearly 240 years of a democratic republic, has intentionally tried to undermine and sabotage the office of the Presidency and the republic itself. No judgement, but fact in his refusal to concede and to assist in the peaceful transfer of power. This is sabotage and a scorched earth policy, which not only hurts the next President, but the republic, and the American people, as I've already stated.
If I have made any unintentional statements regarding the current President and his machinations, then I will publically apologize.
