Are you happy that Donald Trump is no longer president?

Yes. I too prefer Joe Biden over Donald Trump <3

Definitely feeling more peaceful and calmer.

Donald Trump is a disgusting human being.  
An example of a good human being is "The opposite of what Donald Trump is" 
Presidents should at least be a decent role model.  
Biden is at least that.  He is not a trash talker like Trump. 

"now has a president who understands that the spread of corona virus is a big problem"
Exactly which federal recommendations did he change that did anythign at all, about the virus?
Fed mask requirement in fed buildings? Already happening.
More vaccinate then Trump's administrated projected? Actually slightly less but that is due to manufacturing. They can only produce so much. Neither Biden nor Trump had any influence.
There is no doubt that Trump is crass,mean, disgusting, and rude.  But Biden is no pearl either.

Yes very much so ,  Joe Biden has the  Legacies   of Trumps mess to put right  ,  at least Biden  acknowledged  the covid pandemic   and started doing something about it to ensure the safety of the USA  population.  
While all Donald Trump could do was deny  coved  existed , and then told people to drink Bleach ,  how stupid did that sound , Bleach manufacturer's  posted  a danger to health  if anyone followed Trumps   DRINK BLEACH statement  ,  and to think this man was supposed to be acting as 1 of the worlds top leaders..

Joe Biden will be a good thing for the USA  if only people would give the man a chance ...

By the  way I'm  not  an American

Yeah but Biden so far isn’t doing well, not that I’m surprised i mean he has the far left in his ear at all times.
