This "Immigration" expectorating is an MSM/DNC production. The "debate" is worthless. The facts are adulterized, ignored or omitted. This is simply Power Politics and the Media blowing crocodile tears into the ears of the unthinking Emotional and incapable of thinking Ignorant to undermine Trump and his swamp drainage. Which includes every one of them.
"Zero tolerance", "separating children", open borders, asylum, wall building – nothing but boo-hoo and bullshit. Face reality: Democrats want ignorant, dependent voters who love entitlements, willingly trading slavery to government for the cost of their Freedom. Republicans want masses of cheap labor for the multi-billion dollar business and their filthy-rich owners to maintain massive profits. Neither "side of the aisle" gives a rat's ass about Liberty, Rule of Law, Constitutional restraints, the "American Dream" or Shiny Cities twinkling on hillsides. It's about Power. Power to control. Power to punish. Power to dictate how others will be allowed to live. On average, This. Means. You. No "immigration issue" will be resolved until the Ds and the Rs get want they want: Power and Control.
Everything else you're seeing and reading is crap.
