Mitt Romney is often referred to as "Governor Romney" though he's not a Governor.
Mitt was Massachusetts governor from early 2003 for one four-year term. Terribly unpopular at term end (link), it's now over five-and-a-half years since he's been governor. Hallelujah !
Is Romney permanently entitled to use "Governor" while he lives as a rich man year after year on the income from his offshore investments, without working? I think not.
Call him ex-governor Romney if you must. Get rid of the courtesy title.
Romney's a bum.
