Take Sanders’ signature issue: wealth inequality. Despite railing endlessly on the stump about how American corporations are “destroying the national fabric,” Sanders was unable to name even three American businesses guilty of that grave charge. Similarly, while bemoaning how no Wall Street executive has been prosecuted for supposed crimes that sparked the financial crisis of 2008, he could not name any legal statute that they violated.

When it comes to how exactly he plans to “break up” the big banks, Sanders responded with Trumpian vagueness. Saying you’ll recruit “some people who know a lot about this” is apparently the democratic socialist analogue to “We’ll hire the best people.”

Given that he supports closing the Guantanamo Bay prison camp and also believes that Islamist terrorists should be subject to the criminal justice system, what would he do with captured ISIS commanders? “I haven’t thought about it a whole lot.”

Asked to clarify his panegyrics to “fair trade,” Sanders replied “what fair trade means to say that it is fair. It is roughly equivalent to the wages and environmental standards in the United States.” If you want to pay $5,000 for that shiny new iPhone, Bernie Sanders is your guy!...
