If any figure in the United States bears watching over the next couple of years as our political culture continues the radical transformation that led to the election of Donald Trump, it’s Oprah. I believe she’s uniquely positioned, should she wish to commit herself, to seek the Democratic nomination for president and challenge Trump in 2020.

If you think that Trump can be beaten by a two-term governor of a Midwestern state with really good ideas about health care, or by a senator who really attracts young people, think again. The idea that a relatively conventional elected official will differentiate herself from Trump by dint of her seriousness or that an unconventional elected official can out-populist Trump is crazy.

If you need to set a thief to catch a thief, you need a star — a grand, outsized, fearless star whom Trump can neither intimidate nor outshine — to catch a star. We’re through the looking glass here. America is discarding old approaches in politics. Democrats will have to do the same to match the mood to the moment.
