In the latest attack ad released by Mitt Romney’s campaign, President Obama comes under harsh attack from ... Hillary Clinton? The Romney campaign has released a new ad incorporating a clip from the 2008 Democratic primary campaign in which she said, “Shame on you, Barack Obama” in response to Obama’s attacks on her. Romney's ad accuses Obama of launching unfair attacks against the Republican candidate. “He also attacked Hillary Clinton with vicious lies,” the narrator intones, before the Clinton clip plays. The move is sure to prompt a harsh response from someone in the secretary of state’s circle and will rekindle memories of the often-nasty Obama-Clinton primary battle four years ago.
