Is Obama ultimately responsible for the actions of his Administration?

[NightWatcher]

When Treasury, Defense, Education, Interior, Justice or some other department within the Obama Administration does something, can we ultimately say that "Obama did it"?

Examples:
If Holder at Justice cracks down on marijuana possessors can we say "Obama cracks down on marijuana...."?
If the EPA increases the amount of poison it allows in drinking water (examples, people, examples), can we say "Obama increases...."?
Or if Treasury cracks down on fraud and saves bilions, can we say "Obama save taxpayers billions"?

I have tried to be fair in the wording, but I want to know if when Cabinet departments do something if we can say that Obama did something.

1. Obama is responsible for the things done with his enumerated powers.

Foreign diplomacy. Yes. with one caveat on treaties that must be approved by the Senate, which makes them partly to blame.

Legislation. Partly (Congress legislates, and he can not force them to pass a piece of legislation. He can push to get this agenda passed, but can vote for his agenda on the Hill.)

The U.S. has three coequal branches of government. He is not the boss of Congress or the Supreme Court. Responsibility is shared.

2. The administration doesn't include Congress or the Supreme Court. nt

4. Exactly, they are coequal branches.

He as influence in Congress, but he is not responsible except to sign bills or veto them.

3. Sure, ultimately the buck stops with the prez for any administration...

But sometimes people in the different departments should take a fall due to decisions they made.

5. Absolutely. Buck stops with him, just as it did for Bush.

Period.

6. What a loaded question.

Everyone knows if his admin does something good we throw roses and have a parade. If his admin does something bad we find anyone else to blame, preferably a Republican.

I thought everyone had gotten the memo.
