Our capital city is literally blanketed in fog this morning. Barely able to see a quarter of a mile ahead, cars slowly inch along. From Virginia, you can't even see Washington across the Potomac. The entire city disappears.

The fog advisory says it's a couple thousand feet thick in the air. There's zero visibility at Dulles airport.

And what timing for a city in a fog of its own making. This morning things are more uncertain than certain.  The political balance of the Senate. The balance of power. The condition of Democratic Senator Tim Johnson of South Dakota. What to do in Iraq. The President still seeks advice on his listening tour. As he said yesterday, "our enemy is far from being defeated."

The fog is supposed to lift here around noon today. The political fog? No one knows.
