Most evident from Mr. Sanders and the leftward-running Mrs. Clinton in this debate is how completely the Democratic Party’s politics have devolved into nonstop moralistic ranting about the domestic economy. It is bleeding into demagoguery.

Barack Obama, Elizabeth Warren, Bernie Sanders and of course Hillary Clinton have committed the party to a course of individual legal retribution long demanded by the party’s left. Mrs. Clinton: “My plan would have the potential of actually sending the executives to jail.”

These candidates’ nonstop holier-than-thou-ism is in fact a feint. Its purpose is to conceal the reality of seven years of economic under-performance during the Obama presidency. The labor-force participation rate, at 62.4, is where it was in 1977. The Bureau of Labor Statistics’ own vocabulary describes the real world out there: discouraged workers, employed part time, not currently looking for work.

With chutzpah one has to admire, the party that in two terms weakened, if not wrecked, the economy, now presents itself as its savior.
