In my opinion I think U.S president today have less power if they could have than before. The presidents back then would hold office until retirement or until death. Today they can hold office for only two terms for which each is four years long. They still cannot make decisions on their own they need the approval of the two other governing branches. I think the framers of the constitution would be satisfied knowing this is so and that the constitution has been something that has been used to base off democracy appropriately.
