they could get JB clearer, cut his briefings down to weekly/fortnightly instead of daily and make them diagram and photo based as was the format for Trumps infrequent briefings - let him start later in the day, more long weekends and holidays, less actually visiting countries during crisis times and just let him tweet about it instead and then we'd see a clinical speech disorder appear much milder.
I vehemently disagree with Bidens border policy & promotion of hormones and surgeries for minors but think that as a human being he is quite decent - has fallen for the progressive curse of thinking everything out there or new is something we all need to learn to incorporate and not assess with skeptical eyes
If he does the campaign and wins he won't be there long IMHO and if Trump beats Haley to the nomination (likely unless one of the cases goes badly south for DJT) he will shortly be bumbling much more than he is right now because his own Dad had fast advancing dementia at this point and Trump in his civilian mode, living in a resort, still makes big fumbles like the Nancy Pelosi=Nikki Haley X7 and saying that Obama was current POTUS and about to lead the nation into "World War 2"
Shame Biden picked an inept VP too - Kamala is a very weak public speaker, she can do autocue stuff just fine but puts in the lines she wants to become her signature phrases every time in the hopes they will be in italics in children's books soon and when she is off the cuff its very awkward.
Val Demings the ex Florida Cop would have been much more of a connection to the general public and perfect for the wake of the George Floyd incident
