The proper term for Doug Bruce is "mentally ill." To call him "crazy" is insensitive to people who suffer from his condition.
For readers not in Colorado, Doug Bruce is a guy who is hated by the Republicans, and loved by Democrats. He is a Republican, by the way, and Democrats love him because he is who he is.
Today, after demanding a swearing-in that had never been demanded before, Bruce kicked a photographer. Then he demanded an apology from the photographer for taking pictures.
Now, before you go saying, "That guy's crazy" consider this description:

That's from the DSM description of a Narcissistic Personality Disorder.
Unfortunately, there's not a lot of good treatment, so we may just be stuck with this sideshow for the next ten years unless the people of Colorado Springs will somehow find a way to muzzle this nut job.
