Preposterous.
There will always be disparate interest who will seek to influence legislation.
The right to “lobby” is spelled out directly in our Constitution.
On the Federal level, if Congress and the POTUS would stick to the strict bounds of the Constitution there really would be nothing of any merit to lobby for on the Federal level, certainly none of the things that are bringing this nation down right now. Except for the items contained in Article 1, Section 8, everything else would be left to the States.....as it should be so they can be watched closely. This was precisely the intent of the Founders. Read the Federalist Papers for details.....
