It has been said the Lieutenant Governor of a US state should be addressed asGovernor just as a Lt. Colonel is addressed as Colonel. People want to address the Lt. Gov. with the whole title of “Lieutenant Governor”, however, that is very cumbersome. Or should the person address simply be, “Mr. Jones”?
Addressing a lieutenant governor as Governor (name) is really going to displease the governor of your state. Vice president’s aren’t addresses as President because it shorter. Lieutenant governors don’t have a special honorific for their office. Simply address him or her as Mr./Ms./etc. (name) … and identify as the Lieutenant Governor of (state) as necessary.
You might hear the Lieutenant Governor referred to as “Lieutenant Governor Herbert” or “Lieutenant Governor Bell” in the media, but these are phrases used to identify these officials in a news story, not a direct forms of address.
