Former governors are not 'officially' addressed as Governor (name)because there is only one Governor of a state at a time ... and doing do is not respectful of the state's current governor.
This holds true for other offices where there is a single office holder ... The Speaker of the House ... the Mayor of a City .... the Chief Justice of the Supreme Court.
WHEREAS there are many senators, admirals, judges, ambassadors at a time ... so calling a former office holder by one of those titles is not in conflict with a current office holder.
So most correctly he is addressed by his highest, non-exclusive honorific:
Senator (Name) a man who served as Governor twice ...
When Dwight Eisenhower left the presidency he went back to General Eisenhower.
That's also what Albert Gore has done ... he's back to Senator Gore, because he can't be Mr. Vice President.
Bill Clinton and George W. Bush don't have a title to go back to so they are both "Mr."
... and Colin Powell is not longer Mr. Secretary or Secretary Powell ... He's back to General Powell.
This is not formally correct, as the title belongs to the current governor.
However, especially in the Southern states, it is a reference to their former position of public prominence. Ideally it should only be used informally. This is also common for previous Presidents of the US, who are sometimes referred to as President (rather than the correct Former President) after they leave office.
To address just the former Governor: Honorable John Doe If it is an event that his wife is to accommodate him to then the address should read as: Honorable John Doe & Mrs. Betty Doe or, Honorable John Doe & Mrs. John Doe
Governor, or Sir or Maam.
As Lt. Governor.
http://www.formsofaddress.info/former.html#FO011How to Address a Former Governor?Dear Mr. Hickey:What is the proper form of address when writing a letter to a former Governor? When he calls, he says "This is Governor (surname)" even though he is no longer the Governor. I have made it "The Honorable (full name)" in the letter's address block, and "Dear Governor (surname)" in the salutation. Sound right?--- Lonnie Sue ReardonDear Ms. Reardon:His name in the letter's address block is easy. A former governor is The Honorable (full name).But ... the saluation (in this case) is a two part answerPART #1 Only a Governor in office is formally and officially addressed as Governor (name). The correct salutation for a former governor is Dear Mr./Ms./Dr./etc. (name): The reason? There is only one Governor at at time!PART #2 However, if you know it's his preference to be addressed as Governor (name) follow "the preference of the bearer." It doesn't make it correct for others, but I'd honor any person's preference what they are called.For example, if we met and you introduce yourself as Monsignor Lonnie Sue I would think "a monsignor is Catholic priest and always man." SO its "unlikely" you are a monsignor. But I'd call you Monsignor Lonnie Sue to your face: It's not up to me to decide what your name is.However I wouldn't think you'd changed what was correct for others.-- Robert Hickey
You failed to state where you are located. In the US it would be "Governor," or "Governor and Mrs."
Doctor.
I believe the correct address is 'Your Worship'.

The adjective related to the noun governor is gubernatorial. Governor is also used as a noun adjunct and has the possessive form governor's.
Ms. and then your last name.
"My Lord" or "Your Lordship" are both acceptable.
Mr. or Madam President.
