Agree, especially if the Alex matter is as her parents describe, i.e., Kerry only asked their daughter to work for him and she declined - voila! Not a sexual matter - while he's busily diddling a staff member of the finance committee on which he serves. He doesn't have to admit or deny an allegation that hasn't been made, and you can bet the lamestream media won't ask about Senate staffers.
I think that the father of Alex does not at all know the real relationship of his daughter and Kerry. He knows only what she told him.
