Okay, I'll start.
Linguists tell us that most people say "uh" or "um" about once every 60 words. I predict a lot of those oh-ums are going to be edited into videos mocking President Biden. Does anyone want to take that bet?
And anytime President Biden misspeaks about anything, it will be taken as signs of dementia by some dipshits. Funny, that didn't happen when Obama said there were "53 states." Because the attack on Obama then was that he was somehow un-American (i.e. unWhite).
And here is my big prediction (drumroll): If the President of Ukraine should make a video appearance appealing for aid, President Biden will not respond by saying, "I would like you to do us a favor." You know, like the last guy.
I'm not absolutely sure of the above, but I like my chances!
