The National Voter Registration Act requires that states allow eligible adults to register to vote at least 30 days before an election. In Georgia, voters can register at least 30 days before a primary. However, if people want to vote in the general election, they need to have registered before the primary.
For the June 20 special election, in other words, the registration window effectively closed March 20.
That has big implications for a high-profile race to replace Tom Price, who became Trump’s secretary of health and human services. The sixth Congressional district has long been reliably Republican, but Democrat Jon Ossoff, backed by an outpouring of national support, got 48 percent of the vote in the primary Tuesday night. The result has made the district a prime target for a Democratic victory.
