Several states are using an online balloting website based on Microsoft's Azure cloud-computing platform to allow U.S. voters living overseas to cast their votes via the Web in 2012 primary elections. In addition to a now complete Florida primary, Virginia and California will use the system for their primaries, and Washington state will use it for its caucus. To ensure the ballots are from legitimate voters, people use unique identifying information to access their ballots online, according to Microsoft. Once received, the signature on the ballot is matched with registration records to further verify identity."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
