PRESIDENT
veto
an override
Presidents cannot pass legislation. It is congress that makes the laws, and then the president either signs them or vetoes them. But presidents can and do encourage congress to pass certain bills; President Obama, like all presidents before him, has had a number of pieces of legislation he wanted congress to pass. In some cases, they did; in others, they did not.
Because he won by a big margin, he was able to pass legislation.

Absolutely not. The constitution is very clear about that: the President can ask, suggest, bully or beg Congress to legislate, but only the Congress can write (and pass) a law. The president can veto any legislation he doesn't like, which makes it harder for Congress to pass it, but it is still possible to pass legislation over the President's objection.
Write and pass legislation and impeach the president.
Sometimes.
