African Americans grew stronger in their Democratic loyalties and in their numbers. From the 1930s into the 1960s, black voters in the North began trending Democrat, while those in the South were largely disenfranchised. Following the Civil Rights Movement in the 1960s, black voters became a much more important part of the Democrat voter base. Their Democratic loyalties have cut across all income and geographic lines to form the single most unified bloc of voters in the country, with over 90% of black voters voting for the Democratic presidential candidate since 2008.
