The Pittsburgh Steelers, and the Steelers field is named for Teresa Heinz Kerry’s first husband, and Vilsack is a Pittsburgh native. Vilsack says that was it — there was no discussion of his chances of being Kerry’s veep. Vilsack says he has “no control” over the speculation.Vilsack says the way the game’s played, if he says something, then “everybody interprets it” so he’s sticking to talking about his current job — being Iowa’s Governor.
