Next week, at least five states plan to begin an unusual coordinated effort to cancel automatic United States citizenship for children born in this country to illegal immigrant parents.

Opponents say that effort would be unconstitutional, arguing that the power to grant citizenship resides with the federal government, not with the states. Still, the chances of passing many of these measures appear better than at any time since 2006, when many states, frustrated with inaction in Washington, began proposing initiatives to curb illegal immigration…

“The federal government’s failure to enforce our border has functionally turned every state into a border state,” said Randy Terrill, a Republican representative in Oklahoma who has led the drive for anti-illegal immigration laws there. “This is federalism in action,” he said. “The states are stepping in and filling the void left by the federal government.”
