Monetary policy probably won’t be a major issue in the 2016 campaign, but it should be. It is, after all, extremely important, and the Republican base and many leading politicians have strong views about the Federal Reserve and its conduct. And the eventual presidential nominee will surely have to endorse the party line.

So it matters that the emerging G.O.P. consensus on money is crazy — full-on conspiracy-theory crazy.

Right now, the most obvious manifestation of money madness is Senator Rand Paul’s “Audit the Fed” campaign. Mr. Paul likes to warn that the Fed’s efforts to bolster the economy may lead to hyperinflation; he loves talking about the wheelbarrows of cash that people carted around in Weimar Germany. But he’s been saying that since 2009, and it keeps not happening. So now he has a new line: The Fed is an overleveraged bank, just as Lehman Brothers was, and could experience a disastrous collapse of confidence any day now.

This story is wrong on so many levels that reporters are having a hard time keeping up, but let’s simply note that the Fed’s “liabilities” consist of cash, and those who hold that cash have the option of converting it into, well, cash. No, the Fed can’t fall victim to a bank run. But is Mr. Paul being ostracized for his views? Not at all.
