Final answer:
Franklin would argue that American citizens have not fully succeeded in keeping the republic due to a decline in civic responsibility.
Step-by-step explanation:
Franklin would argue that American citizens have not fully succeeded in keeping the republic, based on his famous quote regarding the maintenance and integrity of a constitutional republic. He believed that citizens needed to actively participate in government and exercise civic virtues to ensure the success of the republic. In recent times, there has been a decline in civic responsibility, indicating a failure to meet Franklin's expectations. This can be seen through low voter turnout, limited interest in politics, and a lack of personal and civic virtues.
While strong civic engagement, prioritizing individual rights, and reducing excessive government intervention are important factors, Franklin's emphasis was on the active participation and moral responsibility of citizens. It is the decline in civic responsibility that would lead Franklin to argue that American citizens have not fully succeeded in sustaining the republic.
