Many of the candidates push that line about comprehensive reform. But they don’t explain what it actually means. Last week, The New York Times asked all the Democratic candidates whether they considered illegal immigration to be a major problem. Amy Klobuchar, Pete Buttigieg, Kirsten Gillibrand and Kamala Harris used the exact same “comprehensive immigration reform” watchword, but they mostly spent the rest of their time bashing Trump’s “inhumane” and “cruel” border policies.

They want the emotional validation of being the “good guys” without having to actually lay out their positions on what to do about tens of thousands of people entering the homeland illegally.

They’re unwilling to articulate either an open-borders position or some form of restrictionism. They can hit Trump on his callousness and congratulate themselves on caring more, but that’s where their thinking on immigration stops.

Anyway, this deep concern for the undocumented is fairly new for Democrats.
