Sheriff Joe was wildly popular here a few years ago. Local polls showed voter approval in the 90th percentile, which is amazing given the fact that Arizona is almost a dead 50/50 liberal/conservative split anymore. I voted for him myself. (Not the last election, but the one before)
What changed? For me, it's not the fact that he's a grandstanding buffoon. All elected officials fit that discription to varying degrees and I can overlook that in a Sheriff that is tough on crime. It's not the string of deaths in his jail, but that's part of it. It wasn't the investigation over his alleged wiretapping of the attorney general, but that's part of it. It's not his harrasment of every libreal journalist and conservative talk radio host that has said anything negative about him, but that's part of it.
I think the main thing for myself and others here, is the gradual realization that being tough on crime is not quite the same thing as making a public spectacle of being tough on the inmates themselves to further one's political career. Tent city is not analogous to the Iraq theater. There are dozens of legitimate medical reasons why some people should not be exposed to the summer heat here for extended periods of time ranging from things as common as hypertension and advancing age to things as exotic as ectodermal dysplasia. These conditions would disqualify you for service in the armed forces but obviously can't apply to incarceration because people of all ages and physical conditions get arrested.
County jails also house a fair amount of pretrial detainees. Not all of these people will be found guilty of any crime. While Sheriff Joe has succesfully peddled the idea that convicted criminals deserve no better than to be housed in temperatures that sometimes exceed 120 degrees and fed for 22 cents a day on rotten food, the idea that people should be "punished" prior to their conviction flies in the face of the basic principles upon which our judicial system was founded. This was one of colonial America's orignal quibbles with England for Christ's sake.
Still and all, it's fair to point out that we here in Maricopa county elected him. We have what we deserve. The fact that you guys seem to like him makes our embarassment more perceived than real I suppose
