If Hillary comes across as snarky, self-righteous, and aggressive it could work against her. People already don’t like or trust her so she has to be very careful about sounding and acting like the bitch that everyone knows she is. It could easily backfire on her.
She could take the high road, but of course there is zero chance of her doing that. She’s a hater.
Truism. Goes hand in hand with having a dark soul.
