US elections have been upended by the coronavirus pandemic. At least 13 states have postponed voting and more delays are possible as health officials warn that social distancing and other measures to contain the virus might be in place for weeks, if not months. The states that have yet to hold their primaries find themselves in a seemingly impossible situation as they look to balance public health concerns with the need to hold elections. While election officials routinely prepare for natural disasters such as hurricanes and wildfires, the virus outbreak poses a unique challenge. "Usually when we are dealing with a crisis in elections, it's something that happens and then it's done, said Chris Harvey, Georgia's director of elections. "The difference now is that it's a spreading threat, a fast-growing threat. We don't know where, when or how it is going to end." Primaries scheduled for Georgia, Ohio, Maryland, Indiana, Louisiana, Connecticut and Kentucky have all been postponed to May .
