What is the actual political impact of Sanders' proposal? NOT the political effect it would have if incorporated into the Constitution but the political impact of the proposal existing as atopic of conversation early in an election year one of the features of which is that for the first time in over 40 years serious (or at least potentially serious) alternatives to electoral politics exist. My assumption would be that the proposal will disappear after Election Eve, 2012, for it will no longer have any impact on current activity. The key feature of the proposal does not lie in its content but in its call for people to engage in active support of it. That is, it packages a passive return to the coziness of electoral politics while appearing to be part of the incipient mass movement. It is just one more disguise of the argument that Politics consists of elections, elections, and nothing else.
That makes the arguments for or against the proposal (considered as a possible part of the constitution) exist only in an apolitical realm of seminar discussion.
