Dear Hank
I would like to take this opportunity to offer my congratulations on your election to office. Since we both ran a good race I honestly feel that the voters chose the person they felt most qualified for the position. As I prepare to turn over my duties to you, I want to express my willingness to assist you in any way that I can both during the transition and through your term in office if you should have need. Please give me a call at the office so that we can go over any procedures or protocols which you may have questions about.
Sincerely,
