You're talking about Jim Webb, the same guy who made it a point during his campaign to not allow his son to be used in campaign commercials??? The same guy who refused to mention his son's name on the stump???
The obvious point is you could not be more worng.
You're making enemies with the wrong person here.
Just because Webb didn't use his son for political purposes in the campaign does not mean he is incapable of doing so now. Bush asked him a question about his son personally and Webb responded with a vague talking point about Iraq. It wouldn't have been appropriate to do that if Bush had brought up any other subject, but his son allowed the perfect gateway -- thus, he was being used for political purposes.
This is not a difficult concept to grasp.
