The roiling legal battles over election laws passed in various states have potentially far-reaching consequences: the fate of a key section of the 1965 Voting Rights Act.
The landmark legislation requires the Justice Department to "pre-clear" any changes to election laws in some or all parts of 16 states, mostly in the South, because of their histories of racially discriminatory voting practices. The Justice Department recently used the mandate to block a voter identification law in South Carolina on grounds that it would harm minority voter turnout.
