Over the weekend, Councilmember Grosso heard from a long time resident, who has been voting in D.C. elections since 1964, that she received a notice of no longer being registered to vote from the D.C. Board of Elections. Subsequently, other residents also reached out with the same problem. After looking into it, Grosso found the agency's response inadequate and wrote to the Board today to ask that they address the issue immediately, as early voting for the 2016 election starts next month. See the letter below, followed by an example of what residents received--and the registration card that shows a birthdate in 1800, which is the source of the problem.
Update: Less than a day later, the Board of Elections responded to Councilmember Grosso's letter saying they will be sending a clarifying mailer to voters affected by the original confusing notice. You can see their response below.
