They just don't think being an ignorant jerk is a crime. You have to give them credit; this is one of the most artful trashings of a conservative you'll ever see while at the same time defending him. I've been surprised at the number of lefties and lefty outlets that have challenged this prosecution.
Then again, they may have an ulterior motive. This indictment has all the trappings of a political backfire that will ultimately benefit Texas Republicans. It's entirely possible the Times, David Axelrod and other lefty Perry defenders are painfully aware of that.
