Oh, I though those mails are directed to all listed officials
for an election and assumed this is nothing new to solve.  Sure, this is
entirely feasible.

When token mails are generated GPG automatically verifies whether keys
are usable.  As a result, if someone has an expired key, the script
explicitly notes it and returns an error.

You can't sign votes using your key, as this kills the privacy
requirement.  Instead, we rely on secret token mails being encrypted
using voter's key.  Key only needs to be valid at encryption time,
as you can decrypt messages from the past ;-).
