Final answer:
Research in Alexander's The New Jim Crow indicates that over 23% of the African American voting population in Florida were disenfranchised due to felony convictions.
Step-by-step explanation:
According to research presented in Michelle Alexander's The New Jim Crow, felony voter disenfranchisement led to the exclusion of over 23 percent of the African American voting population in Florida. This level of disenfranchisement had significant implications for elections in the state, with many statewide Florida elections decided by a margin of less than two percent. Such policies originated from legacy methods as seen with the Mississippi Plan, which implemented tactics such as poll taxes, literacy tests, and property requirements to suppress Black voting during the Jim Crow era.
