An all new congress could vote to ban lobbying...Nah, never happen.
No, a Congress can’t ban lobbying ~ it’s a 4th amendment right. Still, that’s no reason former Congressmen should be allowed to lobby ~ they could be crippled in some way as they left office, or shipped to Gitmo ~
You don’t attack the symptom. You attack the cause. Get back to constitutionally constrationed Governance and suddenly lobbyists start hearing “that’s not in our power under the US Constitution”. Lobbyists are then unnecessary for most of what they do now.
May I suggest the following:
1) the Congressman and Senator would have to work in another field (but not law);
2) the Congressman and Senator would be in DC ONLY from June 1 through September 30, WITHOUT any AC at their DC abode or in the Capitol;
3) Bills COULD NOT be more than 100 pages long, would have to be stand alone, and the Congressman and Senator would have read and UNDERSTOOD the bills and their implications;
and finally
4) the Congressman and Senator would have to explain the nonsense they had just passed to their fellow coworkers and bosses every October 1 of each year (right before the bosses’ annual reviews of the Congressman and Senator).
