Final answer:
The presidency has evolved into a rhetorical presidency due to advancements in communication technology, changes in public expectations, and a more powerful federal government. Presidents have used media, from radio to social media, to speak directly to the public and garner support for their policies, which has made the presidency more vocal and visible.
Step-by-step explanation:
The evolution of the presidency into a rhetorical presidency is primarily due to advancements in communication technology, such as radio, television, and social media, which presidents have used to broadcast their message and engage the public directly. Additionally, changes in public expectations and a greater call for presidential intervention in domestic and international issues have contributed to this shift. The emergence of a more powerful federal government and the increasing prominence of the United States in global affairs also played a significant role in the development of a more public and vocal presidential office.
Advancements in communication technology have given presidents the ability to reach an audience beyond immediate geographical constraints. For instance, Franklin Roosevelt's mastery of radio communication with his 'fireside chats' and Donald Trump's use of social media are examples of presidents adapting to new media landscapes to enhance their influence and direct communication with the populace.
Furthermore, the office of the presidency has taken on more responsibilities and power due to major events and crises, like the Great Depression and World Wars, which have necessitated a more robust federal response, often spearheaded by the president. Such events have augmented the stature of the presidency, as have the actions of first ladies like Eleanor Roosevelt who expanded public roles, reflecting broader changes in societal norms and public expectations.
In conclusion, the institution of the presidency has become more rhetorical through direct presidential action, public speeches, and the strategic use of media to build public support for policies. However, this strategy is not without its drawbacks, as it can polarize the public and complicate negotiations with Congress, as noted by political scientist George C. Edwards.
