The author supports her argument by providing evidence from the text. She mentions that some voting laws require specific forms of identification, such as government-issued photo IDs, which can disproportionately affect minority groups who may have difficulty obtaining these IDs. Additionally, the author points out that certain voting laws have been found to disproportionately impact minority communities, such as reducing early voting days or closing polling locations in predominantly minority neighborhoods. These examples suggest that these voting laws may be intentionally designed to hinder minority voters from exercising their civil rights.
