Jones begins with the Constitution's framers, who developed a doctrine
of "separationism" as they defined the presidency. Frustrated by the
essentially executive-free Articles of Confederation, the framers knew
they would write a stronger executive branch into the new government.
But they retained the suspicion of centralized power that had spurred
them to make a revolution in the first place. So, even as they gave
more power to the president, they clearly separated the presidency from
the other branches of government, deeding the legislature and judiciary
their distinct spheres of competence.story
