Black voters and organizers in battleground states say they're anxious about enthusiasm for Biden

Earlier this week, Rev. Greg Lewis, an assistant pastor at St. Gabriel's Church of God In Christ in Milwaukee, physically carried one of his parishioners to the polls inside the city's Midtown early voting center to cast a ballot in Wisconsin's upcoming Democratic primary. Supported by crutches and the pastor himself, the disabled man was one of many residents Lewis has helped vote this cycle.

Through his nonprofit, Souls to the Polls, Lewis has been coordinating multi-church early voting campaign drives after services on Sundays, encouraging more Black residents to vote.

"They are the difference makers," Lewis said on Monday.
