Not my keys to defend, and I certainly won't defend them against someone who hasn't read his book...just seeing the list of the keys is not enough. Allan Lichtman said Biden is up by 4, and he also says that none of them are subjective, including the two charisma ones. He defines it all in his book, so you can't just say that Trump has more charisma...not according to how he defines the keys he doesn't. Really, he should rename the two charisma ones, because he defines them as the candidate is likeable...has "broad appeal.". Trump isnt' likeable, nor does he have broad appeal...but again, you HAVE TO READ THE BOOK to understand it all fully. He has been doing the rounds lately and continues to say that Biden and the Democrats are in the driver's seat, but that the worst thing they could do is have Biden finish his term but then not run...gets rid of the incumbent key.
Lichtman says the best thing is for Biden to stay in the race. Second best thing would be Biden resigns now and Harris becomes President now so that she is President on election day.
