THE WALL STREET JOURNAL: The Federal Reserve Resistance: A recent official urges the central bank to help defeat Donald Trump.

Perhaps you’ve seen former Chairs of the Federal Reserve defending the central bank’s independence and foreswearing all political intentions. Fair enough. But then what are we to make of former Fed monetary Vice Chair William Dudley ’s marker that the Fed should help defeat President Trump in 2020? That’s the extraordinary message from the former, and perhaps future, Fed grandee in Bloomberg.

“Officials could state explicitly that the central bank won’t bail out an administration that keeps making bad choices on trade policy, making it abundantly clear that Trump will own the consequences of his actions,” Mr. Dudley asserts. We also think monetary policy should focus on prices rather than trade. But Mr. Dudley seems to be saying the Fed should do nothing to assist the economy even if it heads into recession. Then he goes further and essentially says the Fed should join The Resistance.

“There’s even an argument that the election itself falls within the Fed’s purview,” Mr. Dudley writes. “After all, Trump’s reelection arguably presents a threat to the U.S. and global economy, to the Fed’s independence and its ability to achieve its employment and inflation objectives. If the goal of monetary policy is to achieve the best long-term economic outcome, then Fed officials should consider how their decisions will affect the political outcome in 2020.”

Wow. Talk about stripping the veil. These columns wondered if Mr. Dudley was politically motivated while he was at the Fed, favoring bond buying to finance Barack Obama ’s deficit spending, urging the Fed to intervene in markets to boost housing, and keeping interest rates low for as long as possible. And now here Mr. Dudley is confirming that he views the Fed as an agent of the Democratic Party.

A key lesson of the Trump era is that every single allegedly neutral, nonpartisan, super-professional institution has turned out to be, in fact, a bunch of partisan hacks shilling for the permanent political party. Voters can be forgiven for adopting a “burn it all down” attitude in response.
