Ballot TRACE (Tracking, Reporting, And Communication Engine). You enter your name and birth date, and it tells you the status of your ballot. As the readout at left notes, my ballot for Tuesday's primary has been received and recorded. As an added bonus, you can have the site e-mail you or text you with ballot updates.
This strikes me as a pretty modest, inexpensive step an elections division can take to increase voters' confidence. Kudos.
