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.
