The Harris campaign has yet to put a full stop to the issue, which has riled up social media users

Hey! This should be in the Grammar thread.
If it's singular, Harris's. If it's plural or a group name, it's Harris'.
For the possessive form of plural nouns, the rule is straightforward. You only add a trailing apostrophe. So, your morning routine of scooping out kibble for your three pooches could be described as preparing the
dogs’ breakfast. (I.e., you would not write the
dogs’s breakfast.)
But there are options for the possessive of a singular (proper) noun which already ends in s (or z). Thus, one could write
James’s car or
James’ car. Either is considered correct.
Pronunciation, however, is a bit more contentious. Typically, the possessive form adds an “ez” syllable to the end of the word. So if Lois Lane writes an article, it’d be “Lois-ez” article — whether it’s spelled
Lois’ or
Lois’s. However, there’s a school-of-thought (mentioned in the original AP story): if you don’t pronounce the “ez” syllable, then don’t write the apostrophe s; just use the trailing apostrophe. An example would be James and his car. If we say “James car,” then we should write
James’ car. OTOH, there are those who’d insist that the proper pronunciation is “James-ez car.” In which case,
James’s car would be the preferred spelling...
Bottom line: the rules for spelling possessives seem to be more clearcut than the rules for pronouncing them.
