Newt Gingrich has released a new attack ad against Mitt Romney. One would think the ad would try and paint Romney as too moderate or too liberal on issues like global warming, health care, or pro-life issues. Instead the attack ad accuses Mitt Romney as being too timid to lead. Really? That's it? Come on Newt! You've been ticked off at Romney's Super PAC and all you can fire back with is an ad accusing Romney of being timid? I would say Gingrich's version of an attack ad is pretty... timid. What do you think? You can watch the video below.
