Developer Phil Henderson has raised more money than his opponent Tom Greene. The two Republican County Commissioner candidates are facing off in the primary in their bid to face Democrat Alan Unger in the general election.  As of Monday, Henderson had reported raising $8000 through cash contributions and personal loans to his campaign. By contrast, Bend City Councilor Tom Greene was showing $4000. The largest contributions were from the Central Oregon Builders Association, Central Oregon Association of Realtors and fellow City Councilor Scott Ramsay.  Tom Greene told the Bulletin that its harder to raise money now than when he ran for city council; and that a lot of people aren't very interested in funding primary elections.
