Final answer:
The presidency has evolved from a limited office to a more powerful contemporary office, with the executive branch now holding at least equal power to the legislative branch.
Step-by-step explanation:
The presidency has evolved from a limited office to a more powerful contemporary office throughout history. In the early years, the presidency was constrained by constitutional provisions and Congress was the main branch of government. However, over time, the role of the president has expanded, and the executive branch now holds at least equal power to the legislative branch. Various factors, such as the personalities of early presidents, challenges in domestic and foreign policy, and the growth of the federal government, have contributed to the increased power of the presidency.
