Funny, but influence peddling is already illegal in many countries, including Canada, but we openly allow and never bother to police the results of lobbying.
IMHO, if you decide to become a politician, EVERYTHING you do and say should be open to constant and unrestricted oversight by literally everyone. We also should elimnate lobbying altogether and tighten up dramatically influence peddling law, breach of trust law and conflict of interest law and enforce the hell out of them.
As much as you and I may come at this from polar political opposite directions, reality of good government lies on some common ground in the middle. I will repeat (and will forever) the very defining test of good legislation and regulation is what I was told by Sir Roger Douglas on the subject. He stated that they did what they did legislatively and in regulation to recover from economic disaster in New Zealand to these four so important words: "We simply removed privilege". You will note that he is from a different part of politics and there is/was no partisan or other qualification to what he said, AND WHAT HE DID.
