President Trump will soon learn what it means to cut a deal with Sen. Chuck Schumer, D-N.Y.

Democrats will not be satisfied with amnesty for the 800,000 immigrants who entered illegally as children. They will push to expand amnesty, bit by bit, to cover nearly all 11 million illegal immigrants in America. Trump will find that his deal to codify DACA won’t earn him lasting love from Democrats and immigration activists, but merely spur demands that he go further, and stoke outraged attacks if he doesn’t.
