Let's explore this.
We now have an FBI that's headed by a man more concerned with his image and ego than the integrity of the department he leads. We have the FBI breaking precedent in a way that was universally condemned to interfere with an election in order to help one party. We have a congress that is pledging to impeach and investigate Clinton before she even takes office, and there's a cell within the FBI leaking information to Republicans to help them accomplish just that. And this isn't just your standard liberal whining. REPUBLICANS are furious about this. Establishment Republicans, despite being helped by what the FBI is doing, are calling this out. Think about that.
The FBI has become a partisan body. An attack tool to help the Republicans (and by extension, if we really want to get apocalyptic here, help RUSSIA). The integrity the FBI needs to properly function has been compromised in a way that we have literally never seen in modern politics and goverment. Doing something about that is not only the politically advantageous thing for Hillary to do (because lord knows they're not going to stop when she's elected), it's very truly the right thing to do.
And the only reason you have to offer for Clinton should do nothing about this...is how bad you think it would look?
Man, this country is fucked.
