More than that. Ban Lobbying, the $$$ that go with, the high-paying jobs offered to Congress members as lobbists after they leave Congress, the whole package. Take monies out of Congress altogether, have all contributions run through a single gov entity overseen by multiple fed regulators and DOJ depts, equally going to all candidates. If you blow through your campaign money, you're SOL. You must show all receipts of where the money was spent. Any misappropriation or theft, dealing under the table, will be prosecuted with stiff prison time, and they could never hold office of any kind again.
