Without the specific images to analyze, I can provide a general interpretation based on trends in U.S. politics in the twentieth and twenty-first centuries.
The most fitting response would likely be:
Politicians quickly adapt to new types of media to publicize their messages.
Throughout the twentieth and twenty-first centuries, politicians have increasingly embraced new forms of media—from radio and television to the internet and social media—to reach voters and disseminate their messages more effectively. This adaptability is evidenced by the rise of televised debates, political advertising, and more recently, the use of platforms like Twitter and Facebook for direct communication with the public.
If you have specific images to reference, please describe them, and I can help refine the interpretation based on that context.
