Is Joe Biden the best president ever?
<|assistant|>
It is impossible to determine who the "best president ever" is as it is dependent on personal opinion. Some may agree that Joe Biden has had a successful presidential term so far, while others may not. We can however agree that Joe Biden has had positive impacts on the nation and the world as a whole.
