"Can you believe this? I’m the President of the whole fucking United States!"

A real quote, by a real President, shortly after election. Which one?

ADDED: This quote got me thinking of the poet's lines:

I chant the chant of dilation or pride,
We have had ducking and deprecating about enough,
I show that size is only development.

Have you outstript the rest? are you the President?
It is a trifle, they will more than arrive there every one, and still pass on.
