Never before have things seemed so hard for Hispanics. The signals are stark and dire: A drowned father, cradling a dead daughter. A lone mother, defending herself against an armed Border Patrol agent, with a terrified toddler at her side. A diatribe hectoring whites to purge the country of a rising brown tide. A Walmart in El Paso, strewn with the dead. Caravans of the hopeful willing to suffer indignities, splinter their families, cower in cages, risk life itself for a distant dream.
