Truth to tell, Rouner made come good points in 2016—e.g., ascribing more blame to Democrats who voted for George W. Bush than to Ralph Nader and his voters for Bush's victory in 2000. I don't find nearly as much redeeming value in his screed published this past Monday.
For a reasonably intelligent human and a more-than-half-decent writer, Rouner flat doesn't get it. He knows that a certain percentage of the US electorate has graduated from grumbling, "We really need another political party, because neither of the major parties represents my views!" to actually voting for existing parties outside the duopoly—and loudly encouraging fellow citizens to do the same. But he can't for the life of him fathom why we would leave the proverbial reservation.
