From the beginning of 2007 to the middle of 2008, the monetary base controlled by the Fed has grown only 1.6 percent at an annual rate. The basic M1 money supply has been flat. This amounts to a long-run liquidity squeeze. The credit-crunched economy desperately needs cash. But the Fed is not providing it.

Over the past three months, the central bank has stepped up a bit to a 4 percent to 5 percent growth rate. But that is still way too little in today's confidence-lacking banking environment. Everyone is hoarding cash rather than putting it to work. McCain should highlight this point.

He also should address all the Americans who might be worried about their bank accounts. He should propose that all deposits be guaranteed by the FDIC, at least temporarily. He might also suggest that G-7 central banks guarantee all inter-bank loans for regulated banks. (Hat tip to Wall Street economist John Ryding.)

He also should put Obama's tax hikes and trade protectionism in historical context. Under Herbert Hoover, taxes were raised, trade protectionism increased, and the money supply contracted. Sound familiar? Obama's tax hikes and trade protectionism are Hooveresque.

Right now, McCain sounds austere when he addresses the economy. Tomorrow night he must sound expansionary for economic recovery. Tax cuts, free trade and money growth -- those are the pillars of recovery. An across-the-board tax cut for individuals and businesses will boost jobs at home and our competitiveness worldwide. Free trade benefits both consumers and businesses. The Fed's money supply must keep expanding.

That message gives McCain a fighting chance.
