This election, like a lot of elections before it, may come down to which candidate voters think might help them with their grocery bills and housing costs — the essential stuff of everyday economics. That’s what people around the country say — and what they tell pollsters too. But the fact that life feels expensive right now is not just something voters are talking about. Campaigns are too. Kamala Harris just released an ad focused on how hard it is to own a home in the United States and an economic policy aimed at curbing prices. And Donald Trump has been on the trail touting his economic record. So, this week on “The Run-Up,” we spend time talking with people who feel the economy is not working for them — and talking to Jason DeParle, who covers poverty for The New York Times, about how the candidates say they’ll help the poorest Americans.
