President Bush came to Washington promising to be a uniter, but public opinion polls show that apart from a burst of camaraderie after Sept. 11, 2001, America is more bitterly divided and partisan than ever.
So the bad news is that it is hot and sticky and muggy. Your skin makes tearing sounds when you get up from a plastic chair. On the Metro, you start to tell people apart by how they smell.
Both athletes were stars. Both faltered, then staged dramatic comebacks -- displaying the tenacity that separates heroes from also-rans. Both now face drug charges that could end their careers.

When George W. Bush takes the podium tomorrow night to deliver his sixth State of the Union address, what are the chances he will say this? "The war in Iraq has been one gigantic mistake. I am sorry I got us into this mess. I am going to bring the troops home right away."
Whenever the United States goes to war, pro-war and antiwar advocates immediately reach for different history books. Hawks always equate the situation to a Hitler-Chamberlain standoff to show why hesitation can be fatal. Doves invariably pull the Vietnam War off the shelf to argue that plunging...
