If the Democratic challengers in Georgia’s two U.S. Senate races pull off victories Tuesday, it will be in part because of people such as Bill Boles.

After standing in line for more than 30 minutes to vote in November’s general election, Boles, 62, a Black man and a chef at an assisted living facility, returned to his polling place in Atlanta’s suburban Gwinnett County on Dec. 15 — a day after early voting for the Senate race began — to cast his votes for the two Democratic candidates, Raphael Warnock and Jon Ossoff.

Boles said he was "really eager” to go back to the polls for a second time in two months, because of extensive efforts by Democratic organizations to get people to the polls and because those efforts have helped potential voters to understand how critical their votes can be. The stakes couldn’t be higher: if Democrats win both races, the party would control the U.S. Senate.
