This question already has an answer here:
I am often confused when writing a sentence with an "and" or an "or." If I want to then follow the two items/people with what they are doing, do I have to use commas to break off the second item/person so that the reader doesn't think that the action only applies to the second item/person? Which example found below looks correct? It is tricky because the sentence is long.
"The school does not allow the president, or the vice president, to vote in the election."
"The school does not allow the president or the vice president to vote in the election."
