Oregon Election Equipment Vendors


Oregon Election System Vendors
How Do They Perform?

Oregonians vote on paper ballots, but our ballots are counted by optical scanners and central tabulators. Both these devices operate using software produced by our voting system vendors, ES&S and Sequoia. The contracts governing the sale of voting equipment to Oregon counties prohibit disclosure of the vote counting software used to operate the vote counting equipment. The software is deemed a "trade secret" and is not reviewable by the public or even by our election officials. Moreover, as a "trade secret" the vote counting software is also exempt from Oregon Public Records laws.

The vendors who produce and supply Oregon's voting equipment are ES&S and Sequoia. This resource page provides documentation from news reports and other primary sources on equipment performance and related issues for each of these vendors.


ES&S

The following links provide extensive documentation of ballot programming errors leading to miscounts. The errors were only caught by a verification procedure where officials hand counted the paper ballots. The vast majority of the errors were made by ES&S.
