And although the famously private Kennedy did not want to disclose financial information, the Daily News did a back-of-the-envelope calculation based on public records and estimated that she is worth about $100 million.
Maybe she hasn't voted much, but surely she has used some of that money to support the New York Democrats financially, right? Actually, the Daily News found that she has made only one donation to a political candidate -- $1,000 to City Council President Christine Quinn.
Kennedy's lack of involvement in New York Democratic party politics over the years may help explain why she has taken some hits from Democrats, like Reps. Anthony Weiner and Gary Ackerman.
"I don't know what Caroline Kennedy's qualifications are. Except that she has name recognition, but so does J.Lo," Ackerman said when Kennedy first started to express interest in the Senate seat.
Kennedy has been lavished with praise by New York Mayor Michael Bloomberg, but even that has a downside. Bloomberg is a former Republican (now Independent) who has infuriated New York's top Democrats by maneuvering to run for a third term as mayor.
There have even been fictional darts thrown at Kennedy.
On Monday, The New York Times published a letter to the editor purportedly from the mayor of Paris calling Kennedy's Senate bid "appalling," adding, "What title has Ms. Kennedy to pretend to Hillary Clinton's seat? We French can only see a dynastic move of the vanishing Kennedy clan in the very country of the Bill of Rights." But the writer was not the mayor of Paris and The New York Times had to publish an embarrassing correction the next day.
The letter wasn't real, but the challenges of being a New York politician are. Kennedy might just end up wondering why she wanted to do this in the first place.
