Thousands of anti-poverty activists have launched a campaign in May 2018 modeled after Rev. Martin Luther King Jr.'s Poor People's Campaign of 1968. Like the push 50 years ago, advocates are hoping to draw attention to those struggling with deep poverty from Appalachia to the Mississippi Delta, from the American Southwest to California's farm country.
