Federal Reserve Chairman Kevin Warsh apparently relishes a good debate, and the upcoming policy meeting is expected to see some robust back-and-forth. After his first one last month, he told reporters there was a "good family fight" about rates, though central bankers voted unanimously to keep them steady. That's a phrase he has used frequently in recent months as he seeks so-called regime change at the Fed. Since his nomination hearing in April, Warsh has mentioned "family fight" publicly 13 times, according to a CNBC tally. But if the June FOMC meeting was a good family fight, the temperature for the next one could go up a notch.
