I've been thinking. There are two components of inflation- money supply and velocity.The Fed and the government have created a money supply that is historically unmatched. Despite all the Fed's efforts there has been no inflation so all this money has created a giant inflationary bomb. The Fed's only real tool to stop inflation is to raise rates (without going into the weeds about open market operations). A "data dependent" Fed would never be able to catch run away inflation. If a Republican president cut taxes and takes Obama's regulatory foot off the economy, velocity will take off and the Fed will be helpless to put out the inflationary fire that results. Huge currency crisis ensues. Are we stuck in the ultimate conundrum?
