(Portland, OR)  --  Portland's homeless count is to be released today, and Mayor Ted Wheeler expects pleasing results.  Wheeler isn't releasing full details until later, but he has hinted at some positive changes.  Over 50-million-dollars have been spent over the past year in combination with the county on shelters, housing, and services for the homeless.  In the last year and a half, the city has doubled the amount of shelter space it has available.
