power throught the constitution is separated through the three branches. Lengislative Branch, Executive branch, and Judicail branch

legislative branch keeps the president in check the executive branch or the president keeps the judicail branch in check, and the judicail branch keeps the legislative branch in check, if one branch had all these powers they could do unrightuos things and get away with it freely
