In this New York Sunday Times article, Mike McIntire explores the above question regarding the true nature of future New York Governor, Eliot Spitzer.
I could have saved McIntire a lot of time. Seriously. A lot of time.
Spitzer and his ilk — whom we have seen on display in numerous business-related prosecutions in the post-Enron era — remind me of what Ayn Rand observed about socialists:

“[T]he truth about their souls is worse than the obscene excuse you have allowed them, the excuse that the end justifies the means and that the horrors they practice are means to nobler ends. The truth is that those horrors are their ends.”
