When I interviewed Paul Bremer in his office he had almost no books on his shelves. He had a couple of management books, like "Leadership" by Rudolph Giuliani . I didn't take it as an encouraging sign.

People in Congress are willing to shut down the entire government or to make it impossible for a Supreme Court nominee to get a hearing or for routine appointments in the executive branch to go unfilled for years because of a hold placed by a senator.

The biggest issue for me is whether large numbers of Americans can begin to think that government can actually help make the country a fairer place. And that's partly a matter of policies that achieve results in terms of reducing inequality and raising middle-class and working-class incomes, which have been flat for decades. But it's also symbolic and rhetorical, it's whether Hillary Clinton can - or whoever's president - can persuade Americans that it's happening and that they can begin to trust their elected officials a little bit more and their institutions of government a little bit more.

We will have a more just society as soon as we want one.

I would caution anyone who thinks the solution is to get out to realize that Iraq will be our problem, whether we're there or not, for years to come. It will not be Vietnam; it will not let us go home and lick our wounds.

If Hillary Clinton becomes president, how is she going to be able to get the country behind her when she seems like a political figure from another era?

Politics should seize the imagination.
