There are many forms of address salutation, depending on the title or rank of the person you are writing to. You wouldn't address a letter to the President of the United States the same way you would address one to your grandmother. If you want an elected official, college official, or other person in power to take you seriously, you need to respect their office and address them correctly. So
. if you are writing to the President of the U.S., for the address you would write The President of the United States of America, and in your letter you would write Dear Mr. President. Anything less would be considered rude and disrespectful. For more forms of address and salutation http://www.law.georgetown.edu/graduate/documents/Formsofaddressandsalutations.pdf.
