If you voted by mail, you could be one of the 4,000 King County voters whose ballot might be rejected because of a signature problem. If this applies to you, you have until 6pm today to deliver signature documents to the Elections office for your vote to count.

This reminds us of the foolishness of using "signature verification" as a ballot security measure. It is upon this folly that vote-by-mail rests. Many of the rejected signatures belong to the rightful voter, who is either unfairly inconvenienced or is disenfranchised. The remaining rejected signatures were necessarily submitted by someone other than the intended (and perhaps consequently disenfranchised) voter. There are also numerous cases of non-matching signatures that are wrongly accepted. I've documented individual cases, but it's impossible to know just how many ineligible votes slip through signature verfication and are counted anyway.
