Clinton's problem was being the clear frontrunner for so long - it enabled the very potent Republican smear machine to zero in on a single target for months.
It's not a smear machine if they're telling the truth.
I'm not saying that Clinton is as white as the fallen snow, far from it, but every speck of dirt from the last twenty-five years has been dug up and flung at her. Including a lot of bullsh**t - Benghazi comes to mind.
I see you support Trump, so I don't think arguing about this is going to produce anything productive.
