President-Elect Barack Obama arrived in Washington, D.C., over the weekend, which was the first step in what is likely to be one of the most historic inaugural events in American history.

The official inauguration takes place Tuesday, January 20, the exact date stipulated by the Twentieth Amendment to the U.S. Constitution.

The Obamas arrived Saturday and took up residence at the Hay-Adams Hotel, right across Lafayette Park from the White House, which was caught better than any news footage I saw by a tourist with a video camera and posted quickly online.

So begins the YouTube Presidency.

Well, one thing is certain from looking at it: Yes, President-Elect Obama can do massive motorcades!

Here is that video, along with the popular celeb-packed video “Yes We Can,” which was done early in 2008 by Will.i.am.

Curiously, it feels a bit out-of-touch now that what needs to be tackled by the new administration is quite a bit more serious than we all thought back then.
