Clackamas County has a good archetype of opposites on the fall ballot. Democrat Scott Mills, a long-time trade union member and Aurora city councilor, is challenging Republican Vic Gilliam in House District 18; it stretches from just outside Canby all the way into southern Marion County. Rep. Gilliam brings a big wallet to the race, tending to reflect his political philosophy of more for the rich and less for everybody else. Mills, chair of the local painter’s union, is gaining confidence, despite a strong Republican edge in voter registration. Forty percent of the district is in Clackamas County.
