Earle the "attack dog"

I just saw a commercial likening Travis County District Attorney Ronnie Earle - the guy who indicted Tom DeLay - to an attack dog. In any other situation, don't you think Republicans, in particular, would think that that's exactly the right attitude for a district attorney to have? "It's not a crime to be a conservative," is the tag line. (My response was, "No, it's a crime to be a crook," which made my husband snort.)
