Re: Left off the ballot?

May I propose a different angle on the "Left off the ballot problem".
For a while I have been making an informal mental list of the kinds of
code fraud that might occur that are fundamentally NOT addressable by
voter verified paper ballots. They include the following:

(1) Leaving candidate choices off of the ballot presented to the
voter--exactly the issue under discussion here.

(2) Leaving whole propositions off of the ballot (variation of (1)
above ).

(3) Improper randomization or rotation of the ballot, so as to put a
favored candidate at or near the top of the list much more often than
he or she is entitled to. (No voter, looking at only one ballot on
screen, can observe this statistical bias.)

(4) Modification of the wording of a proposition text to reverse its
sense, so that a voter in favor of the proposition when correctly
worded, will vote NO if he bases his vote on the wording presented on
the screen. Maybe this is done only on the Spanish ballots!

(5) Violation of privacy: a specific touch sequence on the screen might
present a list IN THE ORDER CAST of all of the votes cast on the
machine this day.

The point is that there are a lot of possible code frauds that are not
reasonably detectable by vote verification alone.

My suggestion is the OVC make this point publically and strongly: the
bottom line is that the only possible way to know that problems like
these are not written into the code is to make the code public!

I say this because those of us in the voter-verified paper trail
"movement" often speak and write as if vote verification is a silver
bullet preventing all software-based DRE fraud. Partly this is because
the more complex argument--that it prevents a huge amount of fraud--has
been enough to get traction without confusing the issue, and partly I
think it is because the many of us have not completely thought out all
of the ways that fraud might be written into DRE code.

Your message, therefore, is that even though it is not a panacea
either, there is absolutely no substitute for published code.
