Perhaps no battle in Donald Trump's presidency will be as pitched, or public, as the coming fight over undocumented immigrants. If he pursues his stated goal of deporting 2 to 3 million undocumented immigrants, a network of pro-immigrant cities, institutions and activists is poised to make the process as visibly contentious as possible.
Trump will have authority to deport millions. While individual cases can be contested and prolonged in immigration court -- the system is already overloaded -- lawsuits against Trump's executive powers or the implementation of his plan appear to have little chance of success.
Resistance to Trump will be highly variable. The entirety of California, which is home to more undocumented immigrants than any other state, seems to be moving to high alert. In Los Angeles this month, board members for the nation's second-largest school district unanimously reiterated their commitment to "protect the data and identities of any student, family member, or school employee who may be adversely affected by any future policies or executive action that results in the collection of any personally identifiable information."
