If Obama is ever asked: 'Is McCain the best person to deal with Russia?'
He could reply: 'The USSR yes, Russia, no'
This one-liner would be perfect. It's funny, informative, and true. It helps to illustrate how McCain's foreign policy experience is grounded in the past: old conflicts, old enemies, old countries that no longer exist.
In a modern job interview, you don't bother to list all of the job experience you have that is no longer relavent. As a computer programmer applying for a C# programming position, no one cares whether you have over ten years of experience with Cobol.
