By the way, the above was pure speculation on my part.
The stuff I have found refers to a "majority of voters" going for "yes" or going for "no." I haven't seen anything that explains how a non-voted ballot is to be counted. Does a non-voted ballot (no "Yes" and no "No" on the recall question) represent a voter for the question of recall? If it does, it has to favor one side or the other, there is no middle ground between "Yes" and "No" for this ballot.
Does anybody have a definitive answer to how non-voted ballots will be counted?
On 30 July 2003, the United States District Court for the Southern District of California held that Elections Code section 11382, which prohibits a voter who has not voted on the first question from voting for a successor candidate, violated the First and Fourteenth Amendments of the United States Constitution. (Partnoy v. Shelley, Case No. 03CV1460 BTM (JFS), RJN, Exh. S.). Secretary of State Shelley does not intend to appeal the court's decision.

So, it appears the onus is on the YES voters to punch the YES chad. Failure to do so may result in absence of majority of voters choosing YES, and recall requires a majority of voters to vote YES. A non-punch is not a vote YES.
If you vote no on recall, and don't select a candidate, a poll worker will select a candidate for you...
Just kidding!
