Question

select the correct answer. what is the primary source of uncertainty over the limits on presidential power? a. some presidents win their elections by greater margins than others. b. constitutional amendments have greatly increased presidential powers. c. the constitutional definition of executive powers is broad and unspecific. d. some presidents increase power in times of need.

Explanation:

The question pertains to the source of limits on presidential power. Uncertainty over elections can influence a president's actions and serve as a check on power. Constitutional amendments can also directly limit presidential power. A broader and more open - ended definition of executive powers would not limit but potentially expand power. And increasing power in times of need is not a source of limits. Option A (uncertainty over elections) is a key factor that can limit a president's actions as re - election concerns can shape decision - making.

Answer:

A. Some presidents win their elections by greater margins than others.
