Corporatism is corporate power replacing government power, which effectively erodes civilian power. Mussolini thought corporatism better described fascist Italy.
If you look at the FISA story it is fundamentally a story about AT&T and other "TelComs" purchasing immunity from elected officials in order to escape a court decision:
When the rule of law is up for sale then we no longer have a Justice system to be proud of. If this kind of thing isn't reigned in, we won't have much of a democracy either.
I have said repeatedly the one word which defines democrats at their best is Justice. When they fight for social Justice or economic Justice or the rule of law they are fulfilling their raison d'etre. If Harry Reid is mixed up in this then he is setting the worst possible example for his party.
