In the graph below, we display the turnout gap between whites and Latinos, Asian Americans and African Americans in states with and without strict voter ID laws. In general elections in non-strict states, for instance, the gap between white and Latino turnout is on average 4.9 points….
…But in states with strict ID laws, that gap grows to a substantial 13.2 points. The gap between white turnout and Asian American and African American turnout also increases.
The right side of the figure shows that the same thing happens in primary elections — and more dramatically. For example, the white-black turnout gap grows from 2.5 to 11.6 when a state adds strict ID laws. The racial imbalance in U.S. voting expands.
