Republicans might have lost the 2016 presidential election if not for the emergence of Trump, who shook up the party’s longtime platform and forged a new coalition, turning out voters no other recent candidate had. After Senator Ted Kennedy died, Democrats managed to lose a 2010 special election for his seat in Massachusetts, of all places—a failure that some Democrats blamed on the national party. Someday, Republicans will need to choose a new leader, and they may be left with only a shell of a party committee, gutted and stretched to be part of Trump’s personal election apparatus.
