After 44 years in politics, Bernie Sanders has finally taken the plunge. He’s a regular Democrat now. Of course, he doesn’t quite want to admit it. “I was elected as an independent, so I’ll stay [in the Senate] two more years as an independent,” he told reporters Tuesday. Indeed, he still wishes it were possible to organize an independent leftist party in the United States, the way European countries do. “We don’t have that,” he said a little mournfully.
