At the time I thought Clinton was a superior candidate to Trump, so I did message a Clinton campaign member my concerns and was ignored. I posted on a Clinton forum and got blocked for being a right wing troll and was told they were ahead in Arizona and competitive in Texas, so there’s no way they need to be concerned about the states I mentioned. The group think was absurd. No dissent allowed.
I bought Chasing Hillary by a NYTimes reporter and that absurd elitism and overconfidence and refusal to hear any real dissent was a recurring theme in that book. (I wouldn’t reccomend it, but the biggest lesson I learned there was the Clinton campaign played everything so safe. A dozen reviewers checking every joke, every line, every answer so every comment Hillary spoke became devoid of substance and too safe and many good plays were shot down if any of a handful of people disagreed with them).
