Certainly not. New Jersey is the Garden State. Growing up in New York, the vegetable stand owners used to brag that they had the best tomatoes because they came straight from New Jersey. As for the Governor, he's less of a rotten potato than a rotten tomato-fitting for a New Jersey governor-since he said that he "guessed" his favorite food would be "pasta". And pasta usually comes with tomato sauce.
Personally, I think the Governor was being deliberately vague, since judging by his build, he no doubt could ring off his top twenty favorite dishes, complete with preferred method of preparation, without pause. Which is just the way he would eat them all, one after the other.
