As the 12 new senators who took their seats last week are finding out, being a member of Parliament brings with it both perks and liabilities. Along with the comcar, a plush seat inside the chamber and the discreet lapel pin (red for senators, green for reps) that all 226 MPs receive comes another certainty: a steady stream of lobbyists through the door. I witnessed this during three years as a political staffer dealing with lobbyists of all stripes.
