Why Trump Keeps Talking about ‘the Caravan’

“When President Trump began tweeting warnings and threats about a caravan of migrants headed for the border, his own government could not explain what he meant,” the New York Times reports.

Politico: “In pressing the issue, Trump sees a twofold advantage. It’s a way to argue that his opponents have ‘turned a blind eye to the problem,’ as one Republican working on the strategy put it, and also an opportunity to rev up his base. Although Democrats remain strongly favored to win back the House, overhead TV pictures of thousands marching north have them spooked…. Whether any real crisis exists at the border remains a matter of considerable debate.”
