Not only has the Bush administration been purging out-of-favor U.S. attorneys across the nation, it has also been using its DOJ to investigate Democrats far more frequently than Republicans, according to TPMmuckraker. From 2001 to 2006, when Democrats made up just half of all elected officials (local and national) in the country, 79 percent of the DOJ’s investigations targeted Dems. The data comes from a study by two retired professors, Dr. Donald C. Shields of University of Missouri-St. Louis and Dr. John F. Cragan of Illinois State University. “The chance of such a heavy Democratic-Republican imbalance occurring at random is 1 in 10,000,” reported the study’s authors.
