The US Democratic Party is returning to its roots. During the previous administration, President Barack Obama's spokesman, Mr Robert Gibbs, derided the "professional left" for wanting things like "Canadian healthcare". Eight years on, the most popular new liberal faces are asking for just that - and much more.
Consider Ms Alexandria Ocasio-Cortez, a 28-year-old "democratic socialist" who beat Mr Joseph Crowley, the heir apparent to minority leader Nancy Pelosi, in a Democratic primary a few weeks ago. Mr Crowley's top donors include Blackstone and New York Life, the insurance firm. Ms Ocasio-Cortez, who took no corporate funds, believes that "money in politics is the existential crisis of our society".
