Reagan also started in radio, so I’m sure that experience helped him as well.
I think it comes from the fact that neither Pres Trump, Pres Reagan and Kari Lake aren’t/weren’t politicians. They weren’t trained and coached on how to answer something without answering it. Talk in circles and show your compassion.
They talk straight. Nothing more, nothing less.
In the real world and private sector, not politics, if you spend your days talking like a politician you aren’t going to last long. No one has time to listen to drivel.
Question asked. Question answered. And you don’t allow someone else to lead you around by the nose.
