Kerry does have a war record and he was there.
Perhaps his family was poor at the time with no political connections, or one of the few that had that and didn't use it or even volunteered for the hard one.
They rarely if ever ask a person to become a US Navy Seal. You have to volunteer. And you have to be there to volunteer.
It's obvious John Kerry was there and tried to be. It is obvious George Bush Jr got to fly a jet and never even had to even worry about that place.
Not for another 35 years.
