At dawn Tuesday in West Quoddy Head, Maine, America's easternmost point, it was certain that by midnight in Cape Wrangell, Alaska, America's westernmost fringe, there would be a loser who deserved to lose and a winner who did not deserve to win. The surprise is that President Barack Obama must have immediately seen his legacy, a compound of stylistic and substantive arrogance, disappearing, as though written on water in ink of vapor.

His health care reform has contributed to three Democratic drubbings. The 2010 and 2014 wave elections, like scythes in a wheat field, decapitated a rising generation of potential party leaders. Then came Tuesday's earthquake, which followed shocking increases of Obamacare's prices. This law has been as historic as Obama thinks, but not as he thinks: It might be the last gasp of progressivism's hubris expressed in continentwide social engineering imposed from the continent's Eastern edge.

Hillary Clinton's proposed solution to Obamacare's accelerating unraveling was a "public option": intensified government manipulation to correct the consequences of government manipulation of health care's 18 percent of the economy. Her campaign's other defining proposal, "free" tuition in public higher education, insulted the intelligence of voters aware that "free" means "paid for by others, including you."
