Where did it go wrong

Where did it go wrong? The role of president I mean. This isn't just about BHO. It is also about those who came before him.

Here are the roles of the president as defined by the US Constitution.
-Commander in chief of the military
-Sign treaties as approved by the senate
-Approve or disapprove bills passed by the legislature
-Appoint ministers as approved by the senate
-Pardon those convicted of crime against US
-Ensure that the law is being executed

That's it

When did we lose our way?
