That’s why Nikki Haley, so covetous of the White House herself, denounced Harris for a tweet last Saturday in which Harris encouraged Americans to “enjoy the long weekend.”“Unprofessional and unfit,” Haley labeled it, because … nobody goes to the beach on Memorial Day? Nobody barbecues? It was as if Harris had done something truly damaging, like abetting a despot intent on subverting American democracy. Harris may have failed, in that one terse tweet, to mention the uniformed men and women who had died in service to the country, but she honored them in other contexts. As for Haley, well, there’s a musty saying that comes to mind. It concerns glass houses.
