Breitbart has the story.  Protecting Melowese Richardson from being caught:

“Millions of Americans were stunned after watching Hamilton County, Ohio voter and Organizing for America volunteer Melowese Richardson proudly admit to casting multiple ballots for President Barack Obama. Recently surfaced emails expose how Organizing for America worked to monitor and block any possibility of a citizen volunteer catching others like Ms. Richardson in the act.

In an exclusive interview with Breitbart News, True the Vote shared emails between Obama staffers discussing targeting specific individuals they believed were associated with True the Vote in Hamilton County, Ohio. Official records obtained by True the Vote indicated that the private citizens on the Obama target list were poll clerks hired by the county–not observers placed by candidates.”
