Mitt Romney is opening up a new line of attack when it comes to personal wealth. Despite his own vast fortune, Romney is suggesting Gingrich's bank account makes him out of touch with the average American. Speaking to CBS News, Romney said, "He's a very wealthy man. If you have a half a million dollar purchase from Tiffany's, you're not a middle class American." Continuing his media blitz with a New York Times interview, Romney warned Republicans about the consequences of nominating Newt Gingrich, saying , "Zany is not what we need in a President." For now at least, Gingrich isn't taking the bait. He says he'll save the attacks for President Obama. Campaigning in Iowa yesterday, Gingrich said, "My campaign is going to focus on positive ideas and positive solutions and I'm frankly taking the gamble that the American people care about actually solving our country's problems, not just watching politicians beat each other up.
