To keep people from supporting Clinton in the future, to continue shitting on her as she's an easy symbol to go against for the right, and to attack Democrats as well. I'm willing to bet at least 90% of the people chanting "lock her up" or crying about the emails wouldn't even bother to read the emails and would just believe any right wing source that she's guilty, if the emails were still there.Clinton isn't in office so why would they have an agenda to turn us against Clinton?
