As I recall from my college political science class, politics is the legitimate exercise of the will of the people. As representative democracy in the United States has been hopelessly corrupted, we need new politics. What form shall that be? Direct democracy? Facebook polling? Pure plutocracy?
I propose that we add to interest groups which already exist, such as the Sierra Club, by formalizing further power in their hands through delegating voting from individual people to the organization. When an issue is under consideration, such as renewing the clean air act, a direct poll of people is undertaken. The collected votes are counted from people plus the delegated votes of representative organizations.
Perhaps plutocracy would continue to operate. And corruption. The test would be that the people’s will would overcome and out-vote those legitimized expressions of representative will.
