I think the only way she survives is if she has a deal with one group of Epstein's pedo island enthusiasts; basically she will cover for some, rat out others and the side she covered for offers her protection, though I doubt that will do her any good. Even if say Trump through Barr has a deal set up to just rat out the Clinton's and such, then that whole network of power brokers will work to get her in a coffin quickly, and even if she survives, why would Trump leave around a loose thread like Maxwell other than sheer stupidity?
If she talks and rats on everyone, she better do it quickly because her death warrant is already signed.
