If telling the truth changes people’s preferences, that doesn’t seem like the messenger’s fault. Whoever actually did/said the thing that people didn’t like is at fault.
There were a few details that legitimately pissed people off though. I recall her being fed debate questions, as well as efforts to undermine Sanders. Those are Hillary’s fault for doing them, not WL or Putins fault for showing people.
This community's depth of political reading is super disappointing.
