It’s not the bunga-bunga that gets them. It’s the bonds. Looks like Italy’s beleaguered prime minister, Silvio Berlusconi, is the latest to learn that. He squeezed his quickly cobbled together austerity package through parliament, but at the cost of his governing coalition holding together. What months, or is it years, of partying in questionable taste and the after scandals couldn’t do to him, the yield on his country’s sovereign debt could. Berlusconi has offered to resign, albeit at a time uncertain. Investors have spoken. Electors, it seems, weren’t consulted.
