Final 2006 Partisan Rankings for Columnists
Partisan: "a firm adherent to a party, faction, cause, or person; especially: one exhibiting blind, prejudiced, and unreasoning allegiance."
Lying in Ponds analyzes, tracks and measures Democratic and Republican bias and partisanship of a selection of regular political columnists from various sources, including the New York Times, the Wall Street Journal’s OpinionJournal, and the Washington Post. Here is the methodology used.
For the second year in a row Paul Krugman and Molly Ivins were the most partisan columnists in the U.S., they switched places in 2006 - Molly Ivins went from #2 in 2005 to #1 in 2006, and Krugman went from #1 in 2005 to #2 in 2006. The top four most partisan columnists are:
1. Molly Ivans (Democratic bias) - Creators Syndicate
2. Paul Krugman (Democratic bias) - NY Times and
Joe Conason, tie (Democratic bias) - NY Observer
3. Ann Coulter (Republican bias) - Universal Press Syndicate
See the top 20 here. Note that David Brooks (NY Times), Charles Krauthammer (Wash Post) and George Will (Wash Post) are the most non-partisan unbiased columnists, and they criticize/praise Dems/Reps with almost equal frequency.
