Jonathan Blitzer spent a week in Mexico with the so-called caravan—a group of about five thousand migrants, most of them from Honduras, who are making a dangerous journey on foot to the U.S. border. Donald Trump, who has described the caravan as “invaders” who might include terrorists and criminals, is using the issue to galvanize Republicans for the midterms. The reality, which Blitzer describes to David Remnick, is remarkably different: exhausted people walking thirty miles a day in sandals and Crocs, sleeping largely in the open, and wholly dependent on townspeople along their route and a few aid groups for food and water. They travel in a group for protection from kidnappers, criminals, and the notoriously severe Mexican immigration authorities. They know little about how their trek has been politicized in the U.S. Those who make it to the U.S. border will likely be greeted by an overwhelming show of American force, but, for these migrants, almost any uncertainty is better than the certain poverty and violence of their home country. Plus, a group of progressive women in rural Texas has been organizing in secret, but some of them are ready to speak out.
