The alleged hacking of governor Sarah Palin’s Yahoo email account has sparked a media feeding frenzy. Rick Davis, lobbyist in chief for the John McCain campaign for US president, has described it as a “shocking invasion” of her privacy, and the FBI has confirmed that it is looking into the matter. But Sarah Palin cannot do much about the media speculation, because it appears that, when governor of Alaska, she conducted official state business using her private Yahoo email account.
