There are various techniques to do this, but that must be the goal.
Being “scary good” also works. As said by Don's teammate Sandy Koufax, “Pitching is the Art of Instilling Fear.” Same objective as Don's, but he never threw at batters. He was so good he did not have to.
We don't have many on our side who are “scary good”. I think Trump could be described that way, and that was why so many would stop at nothing to get rid of him. His political instincts were so dead -on that he literally frightened his opponents.
In contrast, most Republican politicians are less talented or even mediocrities. They instill fear in nobody. So they need to be willing to muss their hair if they want to win.
