Ever since Arizona passed Senate Bill 1070, one of the toughest anti-undocumented bills ever signed into law, the state has been known for pioneering the kind of draconian tactics that the Trump administration is now turning into federal policy.

In the weeks and months following Election Day 2016 — as progressive groups suddenly found themselves on defense, struggling to figure out how to handle America’s new political landscape — Garcia was inundated with calls for advice.
