Recycling 2006 post due to recent mention in Scalia story:

Here's a PDF of an affidavit about some recent experience with Sequoia optical scan machines. Paragraphs 8, 9, and 10 are particularly startling. (There's a longer article at Florida Primary Recount Reveals Grave Voting Problems One Month Before Presidential Election that covers more ground about the affidavit and why the tests were made.)
I think Sequoia should be decertified by the states that still accept their products.
FYI.
