I think the Newt Gingrich/Mitt Romney campaign is the most mutually destructive relationship since that of (the admitted fictional, but are Newt and Mitt real, genuine human beings?) Romeo and Juliet. Like the star-cross'd lovers of the Bard of Avon's tragedy, Mitt and Newt seem bent on a path to mutual destruction. Unlike the hapless, loveable Romeo and Juliet, Romneyo and Newtiet's (insert "Crapulet" joke) destruction is not a tragedy... although the fact that they are the frontrunners in a political primary surely is. The 2012 GOP presidential campaign is one long, extended tragicomedy. It just remains to be seen if Romneyo supporter Suredoucheyo survives the third act.
Two campaigns, both alike in perfidy,
In fair Amurka, where we lay our scene...
