Today's large donation to Healthy Kids, Healthy Portland, the campaign proposing Measure 26-151, which would fluoridate Portland's water supply, comes from Upstream Public Health.

Upstream, a Portland non-profit, is the group that started the fluoridation movement rolling last year in clandestine talks with then City Commissioner Randy Leonard and Mayor Sam Adams.

Filings with the state show Upstream bought $47,000 worth of television and radio ads for Healthy Kids on May 7 and reported that as an in-kind contribution yesterday. 

Healthy Kids, Healthy Portland has now raised $801,000 this year, while Clean Water Portland has raised $257,000.

Ballots will be counted May 21.
