CNBC's Jim Cramer rants on Jamie Dimon's day in D.C.

I bet Cramer could give an impromptu 20 minutes on the meaning of life and barely break for air. Here he is insisting that JPMorgan's trading mess has made CEO Jamie Dimon a loser - despite a less-than-hostile reception during his testimony before the Senate Banking Committee. From DealBook:

On Wednesday, Mr. Dimon received a warm welcome from Republican lawmakers, suggesting that his status as Washington's favorite banker remains intact. Some Republicans praised JPMorgan for navigating the financial crisis better than other Wall Street firms, and even sought Mr. Dimon's advice on fixing the economy. The chief executive, faced with more challenging questions from Democrats about gaps in risk management and his own leadership, both apologized for the mishap and defiantly defended his bank and its reputation.
