Just a sidenote on the "paralysis and chaos": given the angry reactions fron the right, if there's going to be trouble it will certainly come from those quarters more than from the left, as people do remember what Bertinotti obtained by rocking the boat the first time around (that is, nothing). Lega Nord did the same mistake with the first Berlusconi-led government, and they were very cautious not to repeat the mistake the second time. You can expect the same from centre-left parties, especially seeing these results. There will be noise and "ado" all over while defining the government, as it always happens, but after that, I expect a few years of quiet work.
Magical thought goes a long way with demagogues.
The comments about paralysis, about the need for a caretaker government, about the risk for "serious economic reform" and the other points I make would NOT have been made about Berlusconi. Yes you'd have had comments about the unexpected come back, but not these aspertions on his victory. In the long run, we're all dead. John Maynard Keynes
