I first knew Donald Trump could be president of the United States when, poking his finger at the air for emphasis, he said in the most confident tone possible: "I will build a great, great wall along our Southern border, and I will have Mexico pay for that wall. Mark my words."
That was June 16 2015, the day Trump announced his candidacy. Trump descended the escalator at Trump Tower like a shepherd summoned to protect the flock. The country was hurting, and here, his supporters thought, was the tycoon ready to roll up his sleeves for the average American. Everything about that press conference screamed, "Don't worry. I'm here now and I'm taking control."
