There's no pretense at objectivity in any of this. Scaife funds both the Tribune-Review and Horowitz himself. In addition the editor, Bill Steigerwald, who gives Horowitz the soft-ball interview here, writes for Horowitz's Frontpagemag.com. None of this is acknowledged anywhere in the paper, so the readers will never know it. At the Tribune-Review, journalistic integrity is discarded for Scaife's big bucks.
I don't know how long these links will work, so you can get the whole series in one PDF file here.
