That is about the only thing he is capable of being in charge of. For me, John McCain is synonymous with the 'Manchurian Candidate'. Let me rephrase that, he has been around so long he is now the Senile Manchurian Candidate.
The poll is set up so that Giuliani is questionable on account of his two divorces, and the only disquieting detail about McCain is supposed to be his age, but McCain dumped his first wife for a younger and richer one...after the first wife had worked hard to keep public attention on the plight of the POWs. Maybe he had good reasons for ending the first marriage--I don't want to judge him--but it is curious that he is getting a pass when others aren't.
