Yes! It looks like Portland voters have decided to keep their water unflouridated, but not everyone agrees! Here is a sample, but you can read the rest of the article here:
“Since the city council approved a fluoridation plan in 2012, a contentious and emotional campaign on both sides of the issue developed, which attracted national media attention. The initial momentum seemed to be with Healthy Kids, Healthy Portland, a pro-fluoridation coalition of more than 100 community organizations that raised some $850,000 in cash and in-kind contributions to conduct an informational campaign for the election. Clean Water Portland, a group representing fluoridation opponents, raised significantly less money, about $270,000. In the end, voters rejected the ballot measure, keeping Portland as one of the most populated U.S. cities not to provide residents the benefit of community water fluoridation.”
