WASHINGTON — The nation’s largest Latino organizations warned Congress on Wednesday that they will keep a report card during the immigration debate next year, with plans to mobilize their voters against lawmakers who do not support a comprehensive immigration bill. “Make no mistake, we will be watching,” said Eliseo Medina, international secretary-treasurer of the Service Employees International Union, which led one of the most extensive Latino voter drives. The report card will show “who stood with us and who stood against us” on immigration reform, Mr. Medina said."
