Ben White of the Politico website has discovered that Wall Street is on edge. And not just because some stocks are way overpriced. (Bloomberg TV has taken to calling such unproven commodities “unicorns.”)

No, the financial crowd thought it had the 2016 presidential election wired: Jeb vs. Hillary, a win-win.

Now they are scared that voters, who they consider a nuisance, might hand Donald Trump the Republican nomination.

Mr. White quoted the CEO of a large Wall Street firm: “I don’t know anyone who is a Donald Trump supporter. I don’t know anyone who knows anyone who is a Donald Trump supporter. They are like this huge mystery group.”

This guy obviously needs an intern to watch TV and brief him. Maybe even somebody on social media.

The CEO went on: “No one really knows why this is happening. But my own belief is that the laws of gravity will apply and those who are prepared to run the marathon will benefit when Trump drops out at mile 22. Right now people think Trump is pretty hilarious but the longer it goes on the more frightening it gets.”

First thought: He probably considers himself a Master of the Universe, but he’s too chickensh** to be quoted by name. How special.

Second thought: Hope my personal assistant doesn’t have any money there.

Mr. White also quoted Kathryn Wylde of the New York City Partnership, a business group, as saying “a lot of these people thought Jeb Bush was a shoo-in and they are upset now because they have already thrown in with him and he is looking a little wilted.”

That sums up the “heads I win, tails you lose” mentality of Wall Street, which is launching a plan to stop The Donald.

Word is that plan involves doubling down on Jeb, so an old gambling axiom applies: Don’t throw good money after bad.
