Brad DeLong provides three theories about the Bush administration.
In brief, theory one is that Bush is Head of State and Cheney is Head of Government, and that’s the way presidencies work best (see Ronald Reagan passim). Theory two is the same, but they are both useless at their jobs. Theory three is that the plan was to implement theory one, but Bush really wants to be Head of Government as well.
Brad’s conclusion: “I don’t believe Theory 1 — I don’t believe that the American government has been honestly and competently led over the past 3 1/2 years, whether by Cheney or by somebody else. I don’t have enough information to decide between theories 2 and 3.
“The frustrating thing is that the elite White House press corps does, in all probability, have the information to decide between theories 2 and 3. Yet with a few exceptions (Ron Suskind, I believe, plumps for theory 3), they aren’t saying what they think. They need to find a way to do so.”
The pictures from the Cassini-Huygens mission get more and more startling. The latest series shows Saturn’s rings in ultraviolet. “The red areas in both images indicates sparser ringlets likely made of dirty, and possibly smaller, particles than in the denser, icier turquoise ringlets.”
