What "electricty deregulation"? If the market were truly deregulated and working according to market pressure, Enron wouldn't have been able to game the system like they did. The electric "market" in CA wasn't and isn't deregulated. Enron manipulated the fake system by working the rules written by the dimwitted politicians in the California legislature, something the regulations practically begged for.
Exactly right. Davis and his cronies are heavily to blame for the failed electric market in California and are desperately trying to pin the blame on someone else.
