For only the 57th time a president was sworn in Monday afternoon. Acting Dean of the Bush School of Government at Texas A&M Andrew Card worked for Presidents Reagan and Bush and served as chief of staff to George W. Bush.

He has a first hand account of just what happens behind the scenes. For presidents and their staffs, inauguration day is packed full of as much work as it is celebration.

"People get to move into offices, they shuffle around, get new phone numbers, get new business cards," said Card.

"It's also a time of cleaning out because there are some people that won't be staying and when they change hands inside the White House some people will say what comes next I haven't made any plans and there'll be angst an concern, but this is a day of tremendous excitement in the White House," continued Card.

Card has seen his fair-share of inaugurations.

"My first one was watching Ronald Reagan get sworn in and then I happen to be working at the white house for his second term and obviously saw 41 get sworn in and then I saw 43 get sworn in twice, so I have great memories of inauguration days."

From his perspective, Card knows the battle doesn't end with the election.

"I can tell you there's going to be a lot of heavy lifting that has to take place in order for the president to be successful in his second term," said Card.

"That's when the blues start to set in. When you realize how tough the job is and it's not just about the issues you can anticipate meeting, it's te one that you don't anticipate that you have to meet."

The president starts his second term with nominations to top positions like the CIA and Secretary of State.
