On Fini: Comparing Fini to Berlinguer is a bit of a heresy. But that's just my opinion.
On Casini: he clearly stated he doesn't want to be part of the maggioranza. Do you think he might change his mind? Isn't the PdL and the Lega enough to govern?
On the "end" of the Berlusconi era: Is it really that over? I don't know if the government might actually fall (I remember in the years 2001-2006 we went close to it many times, but unfortunately it never really happened), but what shocks me the most is that what is happening now in the Parliament is definitely worse than the whole Mani Pulite scandal. I am referring not only to the illegality issues and the Borsellino case you mention, but also the scandal on the apartments. Yet, people are not responding to it. Sure, I was too young to either participate or remember people throwing coins to Craxi and yelling at him "would you like these as well???", but from what I have heard, read, and imagined, it seemed like those years were of actual revolution. Now, everyone is upset, but no one is doing much about it. A revolution is " a fundamental change in political organization; especially: the overthrow or renunciation of one government or ruler and the substitution of another by the governed". Since the people are not protesting that much, and demanding new election, but rather there is a small little tiny chance that the government might change to a transitional one with Tremonti (e anche su di lui ce ne sarebbero da dire parecchie) and Draghi, well as an Italian I just cannot believe that THIS is a period of political change. Either way, FINGERS CROSSED!!!
