Presidents only get to keep this after they have given it.  It is something they often give.  But even though they are allowed to keep it after giving it, they rarely choose to.

I have been observed by every human who ever lived.  Yet no one has ever seen me in person and I’m replaced daily.

I have a tongue, but I don’t talk.
I have no legs, but I often walk.

I can be seen, yet I’m weightless.  Despite my weightlessness, when I’m put in a bucket, I can make it lighter.

I have a broom in my rear,
a pitchfork in my head
Find yourself near me,
you’ll hope I don’t see red
