Noticeably detached Interior Secretary Ken Salazar in a cowboy hat facing a San Francisco chamber of California-based greens is the story, not the debate.  The Obama administration has already lost the argument for additional off-shore drilling.  Diane Feinstein issued her judgment.  Negative.   It wasn't a struggle.   Stacy Delo looks to be enjoying the visual circus.  The good news is that the worldwide slack demand will keep oil prices low for another year.  After that, hyper inflation is a built-in risk, and longer term, drill, baby, drill.  For now, the cowboy hat is the story.   Does a Stetson mean on an Obama Cabinet member the same that a Stetson meant on a Bush Cabinet member?  And what is that?
