it's the only thing that would -except perhaps public financing of elections.
Money and power are absolute corruptors of humanity -and our politics today is driven solely by both.
You can't take the power out of politics ( although Constitutional rule allows for a decentralized distribution thru balance of powers/federalism)
But the money could be gotten out by public financing & ending revolving door lobbying.
Revolving Door
Although the influence powerhouses that line Washington's K Street are just a few miles from the U.S. Capitol building, the most direct path between the two doesn't necessarily involve public transportation. Instead, it's through a door—a revolving door that shuffles former federal employees into jobs as lobbyists, consultants and strategists just as the door pulls former hired guns into government careers.
