In Mrs. Heinz Kerry's defense, I am sure that having reporters after you all the time stinks. It's not a choice I would make for myself, that's for sure. However, by virtue of being married to Senator Kerry and, I assume, being part of his decision-making process in deciding whether or not to run for President, she did in fact choose to put herself and her family into the glare of the media spotlight.
Also, while we all realize that she is not the one running for President, make no mistake that spouses of politicians or political candidates are as much a part of the whole "process" as the actual candidate. Spouses have quite a bit of influence over the candidate, consequently, if the candidate becomes President, that means the spouse will have quite a bit of influence over the President. Whether she likes it or not, whether it's fair or not, whether it's logical or not, and whether we DISers like it or not, the fact remains that the behavior of a spouse can reflect, either positively or negatively, on the candidate/politician.
I agree that the woman is human, and we all lose our tempers, and perhaps it was a well-deserved "shove it". For all we know, this guy may have been badgering her for weeks or even months, and she finally had enough.
One incident is just that...one incident. She must take care not to have too many of these "one incidents" because if they start to add up is when some people will start to take notice.
