Donald Trump’s six-page immigration platform may not be, as Ann Coulter wrote, “the greatest political document since the Magna Carta.” But given the issue’s role in elevating the candidate to a lead in Republican polls, it merits serious attention.

And at least some of the platform’s planks are serious. Trump calls for nationwide use, presumably mandatory, of e-Verify, the government system that is supposed to enable prospective employers to verify a job applicant’s immigration status.
