What I heard was that "Joe" later commented that he had wanted for sometime to put hard questions to a politician to make them squirm. He had his chance. McCain, as he has done numerous time jumped on something to detract from his own record as well as avoid dealing with issues of real concern. So it becomes a matter of judgment. Again, McCain did not use good judgment. He tackled a subject without knowing the details. Actually, that seems to be a pattern. Not knowing, or possibly caring, about the details. His opinion of American voters must be they are so stupid they will accept his word as truth or fact irregardless of the number of times he is disproven.
