President Trump’s immigration proposal has put Democrats in a bind; they know it and he knows it.

Trump’s immigration “framework” — first outlined on Jan. 25 — represents an unusually sophisticated strategy. He proposes to more than double the number of Dreamers granted a path to citizenship, a significant concession to Democrats.

In return, he seeks approval of a set of policies strongly opposed by the left, each of which is designed to stem what Trump sees as a threatening increase in the nonwhite population of the United States.
