The differences are that Trump hasn't much left in the tank and never did have a law degree.
Those difference matter little, there are plenty in Trumps orbit who are making the plans and pushing them out, all that's needed is another muppet for POTUS.
Where Trump gets interesting is right now and the near future; he's cornered, losing support, and will be lashing out and bending reality to protect his reputation and ill gotten gains.
It's more than just his opinions, which are easily duplicated. It's more than just audacity; anybody can lie boldly. He's got a supreme talent for failing upward that I do not comprehend, but I don't see anyone else with it.
Not that I see it turning out well. At best we return to two more-or-less equally unlikeable parties, except this time with one having a massive thumb on the scales.
