Trump's brain is squirming like a toad.
He is not taking the advise from his best Campaign strategists, and called for this press conference to show them that he is the one in charge.
So he took his own rope and hung himself with it.
He's mad because his whole campaign was designed to lie about Biden, and take advantage of the fact that the Democrats were already not comfortable with all of the insults about his age coming from their opposition.
So the Democrats changed course and selected a candidate that is BULLET-PROOF to those insults, as he thought, in accordance to the polls, that he already had a win in the bag. Well that hope sailed the minute Kamala became his opposition.
And so he is now desperate, and knows he is going to have to Lie about his own accomplishments even more, and Lie about Kamala- But The People are not buying it- BECAUSE what he is saying says more about what kind of a horrible disturbed person he is and says a lot more about him than Kamala and her VP pick.
He is just a reminder to the Independents, and Never-Trumpers on both sides of the aisle- THAT WE ARE NEVER GOING BACKI
