The delegates to the Constitutional Convention envisioned the relationship between the president and Congress as both cooperative and antagonistic. They struggled over how to create the proper balance. Governor Morris from Pennsylvania, summing up their challenge, stated: "Make him [the president] too weak: the Legislature will usurp his power. Make him too strong: he will usurp on the Legislature." Over the years the balance of power has shifted back and forth as strong individuals in each branch of government dominated the political arena.
