THOMAS EDSALL thinks that gun-loving libertarians can save the Democratic Party. I’m skeptical. And so, judging by his final paragraph, is Edsall: “If the only upshot of Democratic gains this week is to revive the internecine warfare that has plagued the party since 1968, then it will be a Pyrrhic victory indeed. To avoid this, someone is going to have to persuade the party’s activists to spend less energy fighting one another and more energy fighting Republicans. That won’t be an easy task. But the Western Democrats probably have the best shot.”
