Do the people in the USA elect the leader of the FCC? If so, can't they elect someone better? If not, why not?
Unfortunately no. The FCC Chairman is appointed by the President. Ajit Pai was appointed by Trump.
Edit: the commissioners including the chairman have five-year terms and have to be re-approved by the Senate for each term. https://en.wikipedia.org/wiki/Federal_Communications_Commiss...
