                  We present Scratch \& Vote; (S\&V), a cryptographic
                  voting system designed to minimize cost and
                  complexity: (1) ballots are paper-based and can be
                  printed using today's technology, (2) ballots are
                  universally verifiable without election official
                  intervention, and (3) tallying requires only one
                  trustee decryption per race, thanks to homomorphic
                  aggregation. Scratch \& Vote combines the
                  multi-candidate election techniques of Baudron et
                  al. with the ballot-casting simplicity of Chaum and
                  Ryan's paper-based techniques. In addition, S\&V
                  allows each voter to participate directly in the
                  audit process on election day, \emph{prior} to casting
                  their own ballot.
