I think that this is a better solution than storing the information
with each member (possibly unless you're sure that you will frequently
want to collect the history of which polls a member has taken).  This
way, all of the poll-specific data stays with the poll object and can
be deleted, archived, etc. together instead of scattering a constantly 
growing set of data over the entire membership.
