Take me, for example. I was a big supporter of Clinton in 2012. I even donated to her campaign. But, several times during the 2016 campaign I actually caught myself thinking that I didn't trust her. And, I had to remind myself why I liked her.
So, whatever they did, it was very, very effective. It really sapped a lot of supporters motivation, at the very least.
George Lakoff has written some interesting books on the topic of reframing. I recommend reading some of his work. I'm sure that the science has evolved considerably since 2004, when I first read him.
Yes. This is SOP.

Don't take this the wrong way, but to me that sounds like cognitive dissonance. If you believe that it was actually unfactual information, I would suggest researching what influenced you badly and try to identify that next time.
Most of this stuff has remained the same since Robert Caldini wrote about it in his book Influence. It's just the tactics and strategies on how to apply them.
Which that is the standard strategy for running for office. Discredit your opponent. It goes both ways. Clinton tried many approaches (even some shady ones) to try to discredit Trump. She did a number on Bernie with the DNC's help.
Speaking of the discrediting, even Obama did a fantastic job discrediting Hillary. (Despite turning around and endorsing in this last election.)
