Familiar music tells an emotional story in which each listener will find a way to relate and then associate it with another message when done properly.
This is another aspect of this. Liberals are far more emotionally tuned in to their audience. Liars are exceptionally good at reading their marks, and they can often tell how far to push their narrative and whether their mark is buying it.
Liberals play people's emotional fiddles, and they are generally much better at it than are practical minded people.
FWIW,
I’ve been in Sales for much of my life and I’m very familiar with most of the tactics taught and used.
On balance, I’m not a very good “Salesman”. I simply can’t lie or misrepresent, mislead or intimidate. My success has come from having an intelligent conversations with intelligent people and guiding them to the logical conclusion. I’m all business and I can’t pretend that I care about their dog that just died.
Sales tactics will continue to evolve as prospects learn and grow over time and then revert back to playing on peoples fear and greed.
It’s no different than politics.
