Would Carrie and Fred support fluoridation? The verdict is still out. (Scott Green/IFC)

For any avid readers who have read our coverage of the fluoride wars, we now have results on the latest battle: Portland has rejected fluoridated water by a 20-point margin, with 60 percent of voters against and 40 percent in favor.

This was, according to the Oregonian, the fourth time the city has voted against fluoridation since 1956. The vote makes Portland one of the largest American cities not to fluoridate its water supply, second only to San Jose. Over-under on when we'll have a Portlandia episode on the subject? I'm guessing next season.
