McCain said. “That means he has no understanding of the economy
Absolutely classic Roveism: go after your opponent by projecting your own weaknesses on him (or her).
This is not at all different from a drunken AWOL national guardsman attacking the military service of a decorated combat veteran.
I get the distinct impression that McCain is running on a platform premised on the idea that Americans are idiots, and can be easily fooled by nonsense.
And given that Americans wholeheartedly bought the attacks of the AWOL drunk on the decorated vet, why wouldn’t McCain run on that assumption? All evidence to date is that the assumption is correct.
