Ehhh, we're basically in a brave new world where personal scandals don't really matter much at all. Creating an HRC style "crooked" atmosphere around a random state legislator, small town mayor, or businessman/woman is much more of a lift.
Personal scandals hurt you if you're not Donald Trump. That's where I think we're at.
There's no cult of personality to save, say, Dean Heller if a skeleton comes out of his closet.
I should clarify that there are still scandals that can stick, but they generally need to involve Watergate/Tammany Hall level stuff at minimum and probably violent crime.
Also, if Russian-linked organizations keep doing this over and over again and to more sympathetic victims, it will eventually backfire and generate a sympathy vote for the Democrats.
