There are options for managing ballot access: * Since there is no spoiler effect, you could just let everyone on the ballot. Letting abstentions count as zero votes, obscure candidates cannot win. (Less severely, abstention could count as a fractional zero vote, i.e. 0 in the numerator of the average and 0<x<1 (say x = .25) in the denominator...) * Or require a certain number of signatures to let a candidate on the ballot.
