One incumbent who faces no primary race is District 2 Democrat Calvin Ball. Two Republicans, Reg Avery and Ralph Colavita, however, square off in the primary. Avery, a recently elected member of the Columbia Association, gets our endorsement. A resident of Oakland Mills, Avery is a consultant for government agencies who has served as vice president of PTA Council of Howard County. Avery, who ran unsuccessfully for this office four years ago, says he will focus his attention on schools, public safety and investments on public infrastructure should he be elected.
