Electoral workers at curbside voting in St. Charles County for voters who have coronavirus disease (COVID-19), during Election Day in Missouri, U.S., November 3, 2020. Photographer Lawrence Bryant: "I was struck by the way these poll workers waited for a voter using curb side voting for people with COVID-19 to make her selections on the ballot. To me, they seemed to be giving her privacy by turning their backs and chatting to pass the time. It shows the perseverance of people seeking to have their voice heard during a pandemic and the courage of the poll workers enabling them to do so."
