Joe Conason:

Many if not most Americans have repeatedly expressed an underlying doubt that either party can still serve the public interest. Those feelings are especially prevalent among the independent voters whose support was critical to the recent Democratic victory. To dispel such cynicism and fulfill the expectations raised by their anticorruption campaign, the new Democratic congressional leaders must quickly deliver real government accountability as well as substantial reorganization of their own institutions. While voters may understand that major changes in healthcare, education and environmental stewardship will be difficult to enact under this administration, they will not have much patience for any evasion on reform of Congress.

Whether Democrats can overcome the old habits that have often made them inarticulate and inert, however, remains to be seen. To put it kindly, the signs are mixed.
