If you're having a tough day, and you're looking for something to make you feel better about yourself even if it comes at the expense of somebody else (and their teeth), just remind yourself how much smarter and more rational your city is than stupid, stupid Portland, Oregon:
For the fourth time since 1956, Portland voters reject fluoridation.
Okay, not all Portlanders are stupid. Just 60 percent of them. But deal with it, Portland: Collectively, you're a stupid, stupid city. And enjoy your cavities.
