Obama has recently come under attack from folks like Stephen Schlesinger and Paul Krugman.  I take it as a sign that Hillary is scared.  From Schlesinger's "The Problem with Obama":

There are a number of weaknesses in the Obama candidacy that make his effort seem both inadequate and even perilous for the Democratic Party and ultimately for the country.

First is the effort by the candidate to portray himself foremost as a conciliator. What Democrats want today is a fighter, not simply a mediator. They have suffered enough from the vicious blows of President Bush and the Republicans. What the party needs is a nominee who will take the battle directly to the opposition. Come the fall contest, a candidacy of "friendly persuasion" will be swiftboated into oblivion.

My hope and prayer is that the politics advocated by Schlesinger will be rejected.
