>>>>>It is not required to hold the bible when taking the oath of office for President of the United States. From the wiki:
>>>>>
>>>>> Theodore Roosevelt did not use a Bible when taking the oath in 1901. Dwight Eisenhower, Harry Truman, and Richard Nixon swore the oath on two Bibles. John Quincy Adams swore on a book of law.[3] Lyndon B. Johnson was sworn in on a Roman Catholic missal on Air Force One. Washington kissed the Bible afterwards, as some later Presidents did, but modern Presidents have not—except for Harry Truman, who bent and kissed the Bible upon taking the oath for the first time, on April 12, 1945, as well as at his second inauguration

>Why would they have to swear on "something they believe is higher"? They are being sworn in as President of the U.S., not a deity.

To whom are they making the promising to?
Maybe some believe that they answer to a higher authority than the Constitution if they break their promise to do their best.

I think It's all matter of trying to be accountable to someone higher than ourselves.
I bet way back when it all started, swearing on the Bible had more significant meaning, like you're promisng God you'll do your best.
