It is pretty hard that two voters receive the same token.  It is
calculated using the member name, email address given to the
foundation and a secret key (one for the whole process). (I don't
think the way the token is get has changed).

For this data, having the same token (md5) two different voters
is not possible.  Collisions in md5 have been detected under
very specific circunstances.

If a valid token is introduced as a token (with anything extra
stuff there) to another voter (a fake one), it will be invalid.

Having the list of all voters and each voter checking his or her vote,
should be enough.  IMVHO, Any voter as member of foundation has the
moral obligation to check it.
