I think he has run with the Hollywood/New York acting crowd (which makes him infinitely qualified to represent the people of PittsburghROFL -- yeh, he'll blend right in like Charles Manson in the Trapp family in Austria.
I don't know anything of this Heinz family intrigue which you mention. I will look into it and let you know if I find out anything.
I think I remember reading it somewhere this past summer, that the oldest Heinz son, John--the one who is still involved with Heinz USA, 'distanced' himself from step-daddy's campaign. Be it for business (distancing the Heinz brand from politics) or personal (maybe the namesake leans more to his biological dad's idealogy than mom's hubby). Maybe I misread it...but I only recall seeing two Heinz sons (Chris and Andre) and the Kerry daughters at the photo ops...
PS...if you have a ping list on PA stuff...please add me.
