What is the percentage of US adults who even know who Jerome Powell is?

If only a tiny minority of surveyed adults knew, then I really doubt whether the poll tells us anything useful.

I think that these polls mostly tell us that:

- Trump is polarizing and unpopular

- Congress is always unpopular

- the Supreme Court is popular or unpopular based on how recently they ruled for/against an issue that the respondent is passionate about

- for people in politics, the less well known you are, the less unpopular you are
