Lets create a law that states that bans politicians and presidential campaigns from being able to accept a contribution from any corporation or an association of a corporation (i.e shareholder, CEO, CIO).
Contributions from any single entity should be limitied to a a maximum value of $5000. This will make them work for their votes and not just being bought.
By placing these limitations it will place some of the election power back in the people and away from the corporations.
