Answer: the Spanish speaking people who are here legally. These aliens are not going to go anywhere but Spanish speaking neighborhoods, which means they are mainly going to create problems for people in Spanish speaking neighborhoods.
Nancy Pelosi has a castle with a moat, for all intents and purposes, in San Francisco, apparently Napa, and no doubt Washington D.C. Same with Chuck Schumer. The plebes don’t get within a mile of them. The border problem might as well be something happening in Swaziland. It’s an abstraction to be used–like everything else in their emotionally and morally poor lives–for political, which is to say personal, gain.
With respect to Trump’s announcement of a shut-down hiatus, I of course am left to guess like everyone else, but I think it had two components. One, he was hearing a lot of stories of really good people, like the Coast Guard, having to go to food banks and rely on friends and family. Unlike substantially all Democrats, apparently, he felt genuine concern and compassion. For this reason, I think it is unlikely he will force this on them again.
Secondly, the press was doing its best to make hay of the coordinated propaganda offensive they were able to undertake with an utterly corrupt FBI with respect to Roger Stone. He quashed most of that momentum.
It is most likely he will go ahead and declare an emergency. Tens of thousands of people pouring across our highly permeable border a month qualifies, and no Democrat lawsuit is likely to overturn that. This is the cleanest solution, I think.
But I think Democrats are mistaken if they think that the legal Hispanic vote is reliably Democrat. The open question, of course, is how much voter fraud they will be able to get away with in 2020. I really hope Trump has a plan for this.
