Trump was an election surprise. Expect more.

The election of Donald Trump was, in many respects, the greatest presidential election upset in modern U.S. history. Now, with his presidency reeling amid a special-counsel probe, multiple resignations, an absence of legislative achievements and dismal approval ratings, many Americans already seem to view his victory as the equivalent of a hundred-year flood — in other words, the type of surprise that today’s voters won’t see again.

Except they will. The Trump election likely signals a new era of extreme voter discontent and improbable national election results. Why? Because the so-called American Dream — that each generation would live better than its predecessor — has ended for most of our citizens. Half of the young adults in this country will earn less over their lifetimes than their parents did. Indeed, the whole idea of rising living standards, which defined this country for so long, is a thing of the past for most Americans. More and more voters realize this and are angry about it.
