I was actually astonished to find Mill making exactly this argument against another proposal in erm a later chapter because he considers a possibility and some people have put forward the view apparently, I haven't heard of this, erm in the version that Mill discusses, that the two stage  action where we vote for people who then go to vote for the members of parliament so the individual people don't vote directly for members of parliament but they vote for  people who then have elections an election among themselves.
