Summary of NY Times Op-Ed Columnists 

The basic premise of most of Paul Krugman's pieces is that never in the history of human civilization has a government made a rational economic decision.
Maureen Dowd has an uncanny knack for boiling down the most complex social or political situations into a plot from a 70's sitcom..."current US-Soviet relations remind me of how the Skipper used to treat Gilligan..."
Bob Herbert, writes mostly about social issues.  He oscillates between the death penalty, poor schools, and police brutality with an occasional get well column for George Harrison.
Thomas L. Friedman is all about the Middle East baby.  Whenever he writes on another topic you just want to smack him and say, "Bad Tom, you go back to writing about the Middle East".
Billy Safire is the token smug conservative.  This former Nixon speech writer writes mostly about foreign policy and would dearly love to bomb the crap out of Iraq.
Frank Rich is a maverick.  We writes whatever the hell he wants.
