Attorney General Eric Holder, who announced his resignation on Thursday, leaves a dismal legacy at the Justice Department, but one of his legal innovations was especially pernicious: the demonizing of state attempts to ensure honest elections.

As a former U.S. attorney general under President Reagan, and a former Ohio secretary of state, we would like to say something that might strike some as obvious: Those who oppose photo voter-ID laws and other election-integrity reforms are intent on making it easier to commit vote fraud.

That conclusion is inescapable, given the well-established evidence that voter-ID laws don’t disenfranchise minorities or reduce minority voting, and in many instances enhance it, despite claims to the contrary by Mr. Holder and his allies. As more states adopt such laws, the left has railed against them with increasing fury, even invoking the specter of the Jim Crow era to describe electoral safeguards common to most nations, including in the Third World.
