My “judgement” is based on her interviews, what she says and how she says it. I don’t know her personally.
I don’t know Obama either, or Bill Clinton, or Hillary Clinton, or Al Gore, or John Kerry, etc either but I think I can have opinions about them in spite of that fact.
My guess is that you have heard much more from all those people over the years and have a total of less than 30 minutes of Caroline interviews.
Interestingly, one book she wrote several years ago was "The Right to Privacy" and she has been a private person. I'm surprised she would even want to get involved in politics---she hasn't made a habit of voting or contributing to political campaigns. I'm wondering if she has been pressured by family members to get involved.
BTW, none of the Kennedys have been known for their brain power.
