I’ve met several Kennedys also. Teddy was the worst of the bunch, but there are none I would choose for elective office over a random selection from the general population. As for JFK, all I see in him is that same as what I see in Barack Hussein - a slick image polished by professionals but one that has no connection to reality.
I used to know a woman who worked in the office that managed the Kennedy kids’ trust fund (or at least one of them). Sometimes the kids — Joe, RFK Jr., William Kennedy Smith, Caroline — would come into the office to get a check or do something else related to the trust. She said they were the most arrogant and obnoxious people. The office staff shuddered when they knew they were coming.
