A mistake to prosecute John Edwards?

I will leave it to the legal pundits to disentangle this one.  Instead, I'd like to ask a question first poised by our beloved President:  "Isn't it ever possible to have enough money?"  The answer clearly is no, since no wealthy person ever wants to shell out his own money for anything if it is possible to avoid it.

John Edwards paid upwards of $200 for a haircut.  Couldn't he have rented a cozy love nest for his girlfiriend out of his personal funds?  The man had the largest house in North Carolina! *

*Or was it South Carolina?
