Also, I think Berlusconi isn't out of the woods yet.
He's very close to being a dead man walking; the only reason he isn't all the way yet it because so many people owe him everything (so his base ought not crumble) and because he's so rich and so unscrupulous. The thing with no confidence votes is that if you only narrowly fail, you try again. And again, and again, and again. Eventually the atmosphere of crisis that that ought to create finds the additional votes, one way or another. Of course the opposition may find a way to fyck things up, because that's what they do.
