Drudge himself my be conservative, but his site really isn't. He gives equal smashing to everyone. The reason it may appear unbalanced is that he links to stories that the predominantly liberal media put on page C-17 of the paper. Much like Fox News being trashed for being conservative--the rest of the media is so leftist that nuetrality appears right-wing. Most of his site is only links to others' stories, so I don't know how anyone can really fault him for accuracy. His personal news items are occasionally put out prematurely, but he also scoops a lot of traditional media--stained blue dress, anyone?
The weapons are, or were, in Iraq. No one goes through 12 years of sanctions and a couple bombing campaigns to safeguard a non-existant program.
