it is the President's job to execute the laws & budget that congress hands him, with whatever funding they provide. We are looking now at a dictator if Obama does not sign a budget passed by congress.
It is the job of the President to be a check against the power of the Congress. If Congress passed a bill that balanced the budget by confiscating all private property, should Obama sign it? He is the executor, but also the protector.
What kind of law do you want to draft that reduces corporate influence without also reducing the ability of citizens to organize and lobby?
Simple: require that only HUMAN entities, not legal or financial entities, are allowed to organize and lobby. The Founding Fathers didn't imagine that we would be crazy enough to recognize a nonhuman corporation as a legal person with free speech and all of the other rights.
