It would have been better if the right people in the .gov had the balls or political leaning revoke it, but I'm certain she "let it lapse" only because she knew (or was told) she would have a legal fight trying to get it back. A nice public legal fight she would certainly lose.
I'm not faulting Trump for leaving her alone. He's got a lot of promises to keep and jailing her would take time and energy from stuff that has a real impact on the U.S. as well as gerring her wouldweakening his political cred by making him look petty and vengeful. Also, more house cleaning is needed at the FBI first. Meanwhile I'm sure she knows she and Bill have to STFU or the investigation resumes.
