Latino Groups Warn Congress to Fix Immigration, or Else

“We have worked to build our power and now we intend to use it,” Ms. Murguía said. “The bottom line,” she said, “is that Latino voters went to the polls with the economy on their minds but with immigration reform in their hearts.”

The leaders made it clear they expect quick action in 2013. They said the president and Congress should take up an immigration bill soon after Mr. Obama’s inauguration in January, with an eye toward completing passage of legislation by August.

The leaders said they would continue a joint campaign they led this year to naturalize Latino immigrants and to register and mobilize Latino voters. They said they would send results from the report card to those voters, to galvanize them during the debate and to guide their choices in the midterm elections in 2014.

“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.
