What is not the reason why presidential power has grown?

Americans have grown to rely more on governmental guidance.

Explanation:

Congress is the department of the government that can stop a sitting president from doing what he/she wants. Congress is the only department that can enact a law to limit powers of the sitting president.

Americans don't rely on governmental guidance as they may have in the past. In this era, many Americans are looking towards the president for their guidance. The mass media frenzy is affecting the presidential powers and helps the president to get more support for his policies that he wants enacted and put into law.
