Not excessively right- or left-wing (8)

I believe the answer is:

moderate

(Other definitions for moderate that I've seen before include "Average in amount" , "Reduce" , "Dare me to (anag) - act as an arbitrator" , "Diminish - within reason" , "Medium in amount or intensity" .)

I've seen this clue in The Irish Times and the Irish Times (Simplex).
