This year, Democrats and Republicans are both fighting to convince voters that their party alone can fix what both parties say is a big problem: the Southern border. And public sentiment on the issue is shifting. According to Gallup, 55 percent of Americans want to curb immigration, the highest recorded total since 2001. With that in mind, we wanted to talk with people who actually live and work near the border. So we traveled to El Paso, with Jazmine Ulloa, a Times politics reporter who grew up there. For this week’s show: a conversation on the border about the border, and what people there make of the shifting politics in the battle over their backyard.
