Afterward, House Speaker "Tip" O'Neill (D-Mass) said “I have never seen such extensive lobbying.”

That was in the wake of the 1971 "Powell memo," a blueprint for corporate domination of American democracy, which prompted the corporatists to move to DC from NY.

The left needs to organize better. Infighting hasn't worked.
