We couldn’t ever figure out why the Clintons’ suddenly shut up and went away very quietly. Personal files and misdeeds don’t phase them so their quick exit has been a mystery for 4 years. A threat against Chelsea could be a very real possiblity.
Chelsea's irrelevent. If anything happened to her, both Clintons would spill everything they knew about everything, and they'd have the sympathy of the people even over things they were involved in because they lost their daughter. Which means whoever would go after Chelsea would have to go after the whole family, and that means going after a former president - ain't no way gonna happen.
No, what happened to Hillary is quite simple: a Butterfly Effect.
Something she did that she considered trivial got out of control, hurt a lot of powerful people who went along with her, blew up out of all proportion in being covered up (as her fiascos always do), and then those people finally got fed up with her and dumped her.
Then they used Obama - who was supposed to be Hillary's VP - as the head of her machine, and just continued on without her. The Obama agenda has been the Hillary agenda with Obama at the head, and Hillary dumped on the curb.
SHE demanded the SoS job to stay in the limelight, and stay connected to government power, and to be able to travel around the world getting backing from various powers to try again.
And she IS going to try again.
This year.
Because Obama will not be able to prove his natural born status to the States that now require proof of the candidates.
And Mitt is being helped by Hillary's own people to get the Republican nomination, in order to throw her the election - just like McCain was supposed to do for her.
