You think McCain cannot be trusted. You're out to prove that point by undermining his VP choice. That's called an agenda - to convince others McCain cannot be trusted.
Why not own up to it? I have much more respect for folks who simply put out in front exactly what they're trying to do rather than throwing red herring after red herring in the way.
But this holier than thou approach towards the VP-candidate's family is odd. I'm sure if we looked hard, we could find problems with your family and mine and virtually anyone else which, if presented in the appropriate light, could undermine you as a conservative.
