The SoS has released the latest random sample report for Tim Draper’s initiative to divide the state into six Californias.
Calaveras, Humboldt, Kings, Modoc, Mono, Nevada, and Ventura counties have turned in their raw counts, bringing Tim Draper’s total to 1,083,353 raw signatures (it was 1,038,836 in my first report). That lowers the validity rate he needs to qualify to 74.5% (was 77.7%) and to avoid a full count to 82.0% (was 88.5%). Below 70.8% (was 73.9%) and he doesn’t even get a full count. We’re still waiting for Alameda, Alpine, Amador, Inyo, and Trinity Counties to report their raw numbers. If they bring the raw total up to the 1.3 million claimed, then he needs 62.1% to qualify, 68.3% to avoid a full count.
Also, the following counties have completed their random samples (with validity rates as noted): Merced (66.7%), Modoc (65.4%), Mono (81.0%), Placer (72.5%), and San Joaquin (72.7%). The uncorrected validity rate is 71.8%, up from 70.7% in the first report. When one corrects for duplicates, the validity rate is 66.4%, up from 58.1%.
Speaking of correcting for duplicates, I think I’ve convinced myself that I now understand where the “-1” comes from in the correction factor for duplicate signatures. It’s best explained with an example.
Suppose I have 100 signatures, and I pick 25 of them (one fourth of 100) at random to check. Of the 25 signatures, I find that one person (Mary) isn’t registered to vote, and one person who is registered (John) has signed twice. That means I have 23 valid signatures and 2 invalid ones (Mary’s and one of John’s). The uncorrected validity rate, before the extra accounting for duplicates, is 92% (23/25).
Remember that these signatures were picked at random, so if I found two signatures from John in the 25 I picked, it’s likely that there are three others from John in the other 75. (Well, maybe not likely, but that’s the best estimate.) So John really accounts for 4 duplicate signatures, not just one. But we already accounted for one of those duplicates by calling it invalid in our sample, so we just have to account for the 3 extra duplicates in the unsampled portion.
Also, if John signed more than once in this sample of 25, we can suppose that there are probably three other people in the other 75 who also signed more than once, and the best estimate is that they each also signed five times (one of which is a valid signature in our sample). So a factor of 4 (100/25) for the four people (John plus an estimate of three others) who signed more than once, times 3 (4 – 1) for the fact that one of each duplicate is already accounted for by the uncorrected calculation, means John’s duplicate signature should be given a weight of 12. 12/100 is 12%, so the corrected validity rate is 80%.
Of course, if we found two people in the sample of 25 who signed twice, or if we found three signatures from John in that sample (one that we consider valid and two that we consider invalid), we’d have twice the correction factor (24%), etc.
Now before you start thinking “Gee, if I’m against a petition, I should sign it as many times as I can instead of not signing it at all so as to drive up the duplicate rate, since duplicate signatures hurt more than plain invalid ones”, I have to point out that this is illegal. Election Code section 18612 says “Every person is guilty of a misdemeanor who knowingly signs his or her own name more than once to any initiative, referendum, or recall petition ….” Deliberately signing a false name, while hurting the petition less than signing twice, carries a harsher penalty. Election code section 18613 says “Every person who subscribes to any initiative, referendum, or recall petition a fictitious name […] is guilty of a felony and is punishable by imprisonment pursuant to subdivision (h) of Section 1170 of the Penal Code for two, three, or four years.” So don’t do it.
