that is because you are a slobbering ignorant jackass. Trump already has the "worst president" title while Biden is in the top 20.
Biden is not president. He was never elected.
You consider Biden, who doesn't know what year it is, doesn't know what he is doing, doesn't know who he is talking to, and doesn't know where he is going, tries to shake hands with people that aren't there, tries to wave to crowds that aren't there, can't seem to handle a teleprompter, a staircase, or a bicycle as the 'top 20'?? Maybe in comedy, I suppose.
After all, Carter only barfed on the Prime Minister of Japan, and got attacked by a frog in the swamp (the secret service shot it!).
Then there's Cheny, that likes to shoot at senators.
Then there's Clinton, who got disbarred for perjury.
Then there's Reagan, who started out playing 2nd fiddle to a chimp.
Trump is great for comedy too. The way he trolls the news media and Democrats is priceless!
