This politcal ad for Agriculture Commisioner of Alabama uses a lot of intimidation factors. For one, the man running, Dale Peterson seems to be yelling throughout the entire commercial. He also puts emphasis on some of his words, such as "They don't give a RIPP about Alabama." and "Who would vote for such a DUMMY?" This man is angry, and his anger can intimidate some voters and make them scared of what might happen if they don't put him in charge, so they vote for him.
I found this ad simply by browsing YouTube for bad political ads.
