You made a claim that lobbyists are not subject matter experts. Another commenter refuted that claim with counterexamples. Now you are moving the goalposts and demanding quantifiable data about how many lobbyists have expertise in some domain.
I think it's time for you to counter by defending your thesis, that lobbyists generally don't have domain expertise, instead of demanding increasingly more evidence.
