Fortunately, choosing between these two strategies is unnecessary. There is an alternative to left-right politics and by adopting it Democrats can remain true to progressive principles while attracting millions of voters from the non-ideological middle.

The step beyond the "New Deal," the "Fair Deal," and the "Great Society" is a "Dignitarian Society." The slogan is Dignity For All.

What's required for social change, and it could come from either party, is the kind of political realignment we get once every 50 years. Such realignment pulls a sizeable majority from the vast non-ideological, sensible middle of the political spectrum, and creates a real mandate for fundamental social change. Like those that FDR and LBJ presided over. Like the universal health care and campaign finance reform that we need now.

What core value, what slogan, could move us beyond the toxic standoff that paralyzes American politics today?

The answer lies in a single word--Dignity.
