I’ve only been here for a couple of month and nice bit on accusing me of being a liar, but whatever.
I haven’t seen any, as I would define an attack. I’ve read people saying that she might need more experience or that she’d be better off running for another elected office or that they prefer another candidates.
These aren’t attacks. You’ve made these evaluations yourself about other candidates.
An attack is a driven and personalized comment that is meant to damage somebody. For example, “Sarah is a dishonest quitter, because she quit her term as governor halfway. She probably does drugs.”
Commenting on her finishing her term early is not an attack, but accusing her of doing drugs is, because there was no basis for accusing her of doing drugs.
