Democrats, make a deal with Trump to protect DREAMers

This kind of hopeful thinking is seductive but dangerous. When the legal protection of 800,000 people is at stake, Democrats need to expect the worst, even while hoping for the best. That means assuming that if DACA expires without a fix, the administration will be aggressive about deportations, the Senate will remain Republican, judicial stopgaps will fail, a Republican will win the White House in 2020, hundreds of thousands will be pushed into the shadows and many tens of thousands will be rounded up, detained and ejected from the country…

So a deal that includes money for the wall ought to be a no-brainer for Democrats. Every viable proposal under discussion includes a hefty “border security” element, but not any of them include a literal solid wall spanning the entire southern border. Last week, Kellyanne Conway, a White House counselor, said that Mr. Trump understands that “part of it will be the physical wall, part of it is better technology, part of it is also fencing.”

The wall Mr. Trump promised isn’t going to materialize, and he’s not going to insist on it. Of course, Mr. Trump will say that new border security enhancements constitute a wall. But Democrats can vote for them without following suit.
