I would suggest that if voting were somehow had a positive correlation to liberty (and I would not assume that to be the case) that only those who own property should vote and the only elections that should be held are within a community. The idea that age qualifies you to vote (or any other arbitrary factor such as race or sex) just does not strike true to me. Property ownership ties you to a community and ensures that you will at least try to be a custodian of what you own. Of course voting for "masters" is not something I would endorse anyway.
