As far as I could tell, President Obama gave his speech with almost perfect delivery. It is unfortunate, then, that he could have made such a mistake right at the beginning.
While President Obama is our nation's 44th elected President, he is only the 43rd person to take the office!!
While it may be easy for most to forget, President Grover Cleveland was our nation's 22nd and 24th President, with President Benjamin Harrison presiding inbetween terms as our nations 23rd.
