On April 19th, 2017, Donald Trump had been president for 87 days. His campaign had been prologue for his Presidency, which was prologue for January 6th, which was prologue for his current campaign. He was clear about his desire to be a dictator long before he said the words aloud.
I was mayor of Minneapolis, Minnesota at the time. Knowing that Trump was walking the path of fascists and authoritarians before him, I asked myself what I would have wanted the mayor of Düsseldorf, Germany to have done in 1933.
