Voter Identification Laws and the Suppression of Minority Votes

The proliferation of increasingly strict voter identification laws around the country has raised concerns about voter suppression. Although there are many reasons to suspect that these laws could harm groups like racial minorities and the poor, existing studies have been limited, with most occurring before states enacted strict identification requirements, and they have uncovered few effects. By using validated voting data from the Cooperative Congressional Election Study for several recent elections, we are able to offer a more definitive test. The analysis shows that strict identification laws have a differentially negative impact on the turnout of racial and ethnic minorities in primaries and general elections. We also find that voter ID laws skew democracy toward those on the political right.
