Option 3: plain folks
This statement is an example of the propaganda technique Plain folks because it presents Governor Tyson as an average or common person whom the consumer can relate with, or empathize with: He is a family man and has worked in a certain community.
The author of the propaganda uses this technique aiming to give a sense of trust and comfort to the audience by demonstrating how the Governor's experience is similar to the audience's, in order to sell his or her idea.
