When you go to the polls September 14th (Primary day) and in November, there will be a new wrinkle: modern voting machines! Coming up tomorrow, there will be a demonstration of the new system, which requires voters to use a paper ballot and an electronic scanner. The demo will take place tomorrow from 3-6pm at Bracetti Plaza, 296 East 4th Street (between Avenues B & C). The event is being sponsored by Community Board 3, the East 4th Street Block Association, CODA, District Leader Anthony Feliciano, Councilmember Rosie Mendez, Senator Daniel Squadron and Assemblyman Brian Kavanaugh. For more information call 347-213-2909.
