2) You can resign as president and you're still forever referred to as Mr. President. It's just the way it's done.
Was Nixon referred to as Mr. President after he left? I could be wrong, but I don't think so.
We've had this discussion in another thread.
Formally, neither presidents nor governors get to keep their titles. The rule is if there is only one at a time, then that person gets the title. President Obama. Mr Clinton, Mr. Nixon, etc.
The Honorable is an acceptable honorific which remains in place: The Honorable Mr. Dumbass. Judges, congressmen, generals, etc. all get to keep their titles since it's not exclusive to the current holder.
In private, it's considered acceptable to use any title; all of their friends refer[ed] to President Nixon and Speaker Gingrich. It's considered a courtesy title.
Lastly, people who retire can choose to revert back to a previous title if it's acceptable after the fact. General Eisenhower>>>President Eisenhower>>> General Eisenhower, Ret. Clinton can't go back to Governor Clinton because of the first rule.

While Governor Palin is technically incorrect, she can ask to be called "Her Royal majesty, the Queen of Shit for Brains" if she'd like (see Nixon and Gingrich). Also, if he's referring to her in the third person, then it's acceptable for reporters to use an honorific to be more specific, though appending former would be the non-biased way to go about it.
