What's in a name?

What’s up with the name Dick?  Is the arrogance exhibited by those politicians who go by that name due to the fact that it can refer to the male organ?  

The puppet master Dick Cheney is finally out of hiding arrogantly defending his policies and, again, fear mongering.  Granted, his warnings about the closing down of Gitmo are not unwarranted; but the dilemma of whether to close or not the facility is entirely of his making.  Had the Bush administration made any effort to establish Guantanamo’s legitimacy in an orderly and legal manner, we would not be in this mess.  Fuck you Dick.
