They`d all have to struggle mightily. Beating Obillion$ will be a gargantuan task. At least Newt can take him down in debates. That`s a whole lot more than the awed, feckless McCain could accomplish in 2008.
Not endorsing the Messiah in the debates would be a good start. Do you remember "You don't have to fear Obama as President"? It couldn't be clearer to me that it was McCain's final finger in the eye to conservatives.
