Why aren't the presidential candidates talking about the poor?

Democratic Presidential nominee Hillary Clinton rolled out her economic plan in Detroit Thursday morning. Donald Trump unveiled his plan there earlier in the week. There was one glaring omission from both platforms – poverty. Clinton promised to create jobs with a New Deal-style investment in infrastructure, manufacturing and science. She portrayed herself as a champion for middle-class families, while painting Donald Trump as a friend to the wealthy. But what about the millions of Americans living in poverty? Why are they mostly left out of the economic conversation on the campaign trail? And what is either candidate offering them?
