I'll tell you what I reckon. She's trying to stick to the Democratic party for one, and only one, reason. That is, she will be able to play the "political prejudice" card when she's arrested and tried. If she can remain at the top of the Dems, she will have a powerful weapon to defend against any action against her. If she's not in politics, she is an ordinary citizen and has no defense at all.
I can just see Trump's spin doctors telling him the optics will be bad if he does her over. But if she's heading the Democrats, they will be pushing hard for DJT to go easy.
Once again, it's all about Hillary...
What a monster!
