I want to write letters to Congressmen and women as well as Texas Governor.?

Question

How do I format this letter? What is the right way to format the letter so that it is understood that I am serious about a situation.

Answer 1

I would format it as a business letter.  That should do the trick.  Also be sure to look up the official form of address (e.g., "The honorable _________") for the recipients.

Answer 2

For US Members of Congress, you address them as "Dear (Mr. or Ms.) Smith" unless the person is Chair of a Committee, in which case you address the person as "Dear (Chairman or Chairwoman) Smith."  Sign off by saying "Sincerely" or "Respectfully."  

For the Governor of Texas, you start out by writing "Dear Governor Chimpenstein."  Oh, sorry, that was the previous Governor.
