This is really what they mean. "Lobbying" as a term generally connotes getting paid to do it. When people do it for free, it's more frequently called activism or advocacy.
I actually think a limit on pay might be better than an outright ban. Former members of Congress have skills, experience, and connections that could be beneficial for advancing a variety of social causes. It's the big payday, cashing-out part that stinks of corruption and undue influence.
Are there other individuals who have been primarily known by only their initials? (Excluding authors like J.K. Rowling, etc. where pen names are more common).
