If you want to know what power feels like, try to get yourself driven around in a motorcade. Flashing police chaperone lights form a perimeter as you blaze down an empty highway, waiting cars backed up on entry ramps as you pass. It’s as if the world is holding its breath. For you. Also, rules don’t apply: On a cool spring day, driving down suburban Minneapolis side streets, we run red lights and whip round curves so fast I can barely take in the commonplace American view. Tract housing, big box stores, churches, office parks, semi-​industrial no-man’s-land. Finally, we arrive at our destination, Nine Mile Brewing, in Bloomington, Minnesota. “Let’s go, let’s go, let’s go,” commands someone—a Secret Service agent, maybe—as the motorcade pulls into a loading dock. Politics, I will come to discover in the next few days, involves a lot of backstage spaces: service entrances, freight elevators, places where Very Important People can slip in and out of events unnoticed. Politics also involves a lot of comically fast walking—to wit, at Nine Mile, an entourage of 30 or so are noisily hustling to follow a trim, blond woman in a pristine white suit as she strides nonchalantly past clanging, gurgling brewing vats, aiming for a back office. This is my first glimpse of first lady Dr. Jill Biden: Exiting the sealed chamber of power into the middle of America, a vision of calm amid utter cacophony.
