So much for taking this off the list... :(

No I didn't.

I'm going to have to reply "no comment" here - I haven't read through
your definition in sufficient detail to form an opinion. Skimming it, it
seems reasonable.

Specifically, I said the following, in private email:
------------------------------
Oh, if you want to use some other definition of "if" in statement three,
that's fine too, and I'll accept statement #3 on that basis. However,
then your argument falls down on statement #4, because probability is
defined using mathematical ifs - and if you calculate it some other way,
then you won't get a probability. If you don't get a probability, you
can't use it to accurately calculate the utilities of voting for or
against each candidate.
------------------------------
Notice keyword "if" used several times. *IF* you want to use some other
definition... *IF* you calculate it some other way... *IF* you don't get
a probability. And we all agree on what "if" means, don't we? ;-)
