Akkam’s Razor

There's a VERY legitimate argument that both Romney, Giuliani, as well as the Democrats, if they are smart, should be having with regards to McCain…

He's already hinted that he's likely to be a one-termer.  At the risk of practicing ageism or age discrimination, he's quite old.  His captivity as a POW has certainly had a physical effect on him (particularly melanoma), and if the claims of George W. Bush circa 2000 (8-years ago) are true, his mental health. 

These factors require scrutiny towards his choices for a Vice President, since it's quite possible that person may have to assume the Presidency, either by choice or chance.  The country is essentially voting for President twice.  The GOP would be wise to consider this, and if they are not serious about backing Romney, Giuliani, or one of the B-, C-, D-list candidates, and to shepherd McCain through that process, as that Veep needs to fill Darth Cheney's shoes as well as being the Party's likely Messiah.
