Its pretty standard practice that re-voting should not be

That's not true, in Usenet you can change your mind resp. fix
errors. The most obvious case is sending a vote with a "secret"
address, and then exchanging it against the same vote with a
"public" address, because the votes will be published, and the
address harvesters are everywhere.
this and other manipulation schemes should be minimized
Convincing somebody is not necessarily "manipulation". And if
a candidate does something very stupid during the vote, like
say withdraw, then changing a vote is the natural reaction.
somebody may try technical means to change/invalidate
somebody elses vote by sending bad extra confirmations
The RO handles all these problems. Technical solutions cannot
catch all possible cases of abuse. If that would be possible
then "Sender ID" should work. But it doesn't. Bye, Frank
