Yes, disgraceful is certainly a good word for it.  
I think that the Republicans have focused on her for a very long time.  They know how to do that -- hang on to something like a dog does with a bone.  They ensured that there was a constant stream of negative information coming out about Hillary.  It did not matter that most of it was based on innuendo and fantasy.  
I expected Fox News and other right media to carry water for them, but it's really upsetting that the mainstream media did, too.  This built a foundation that Trump later used -- gleefully.  
The same thing happened throughout the campaign.  Actually, I think that it's a testament to voters that so many voted for Hillary, despite the constant and prolonged media barrage.
