Indeed, however because you must run Emacs with
superuser rights in order to edit /etc/sudoers (i.e.
you won't get your everyday user's Emacs configs) it
can be preferable to use something altogether
different and above all more simple, like nano, which
seems to be the default - in spite of the name (or
perhaps "vi"sudo refers to "visual" and not vi(m)).

If you are dead set on using Emacs, try

    sudo EDITOR='/usr/bin/emacs -u USER' visudo

However then be aware that all tildes (~) in USER's
configs won't be /home/USER, so those have to be
changed to explicit paths unless there is yet another
way around it.

Perhaps the `user-login-name' or
`user-real-login-name' could be experimented with...
