Not necessarily. Presume for a moment that members of a nominating committee enter the nominations; in that situation the currently connected user is NOT the nominator. The procedure, as written, accepts both the nominator and the nominee, so it is possible for someone else to process a nomination made by a third party.
The materialized view solution is more elegant.
