No Bible Used for Obama's Official (if at first you don't succeed) Oath of Office

News outlets reported how confused Obama was while stumbling through the oath of office. Trying to clear up any confusion, the Obama - Roberts team tried the oath a second time. Without the photo opportunity of the world watching, no Bible, Lincoln's or any other was used. The official oath of office was taken without benefit of a Bible. I wonder if that is a good thing for an administration.
