This week, NPR examines public corruption in South Texas. The FBI has launched a task force to clean up entrenched wrongdoing by public servants in the Rio Grande Valley. In the final part of this series, we examine vote-stealing and election fraud.

A new FBI anti-corruption task force is trying to clean up the Rio Grande Valley of Texas. According to the Justice Department, in 2013, more public officials were convicted for corruption in South Texas than in any other region of the country. One of the practices the task force is looking at is vote-stealing.

They’re called politiqueras — a word unique to the border that means campaign worker. It’s a time-honored tradition down in the land of grapefruit orchards and Border Patrol checkpoints. If a local candidate needs dependable votes, he or she goes to a politiquera.

In recent years, losing candidates in local elections began to challenge vote harvesting by politiqueras in the Rio Grande Valley, and they shared their investigations with authorities. After the 2012 election cycle, the Justice Department and the Texas attorney general’s office filed charges.
