The problem is voters have increasingly poor choice or say in the matter. Increasing concentration of wealth has shifted great electoral power to the few, both political parties are dependent on that wealth to finance their campaigns against each other, and ultimately answerable to it, hence there's no real choice for voters at the ballot box (other than on insignificant wedge issues), and it takes a herculean effort to compete in between elections with lobbyists who used to be Congressmen or staffers. That may or may not be specific to America's "implementation", but that's the problem.
