If otherwise permitted by law, elected state officers, other than judicial officers, may use public funds, property or time to post materials in their offices to indicate their opinions or positions on issues, provided these materials do not advocate the election or defeat of a clearly identified candidate for any elective office or a vote for or against a state question or any other question to be voted upon at an election. Mere display of a photograph or similar depiction of a current or former elected federal or state officer, including autographed photographs or similar depictions, shall not be a violation of this section.
