"President follows the same capitalization rules as other titles. A title is the name that describes a person’s position, rank, office, or job. You should only capitalize titles when they come directly before a person’s name, as in President Abraham Lincoln."

"Other than those cases, president should be lowercase. Take this sentence for example: The president lives in the White House. Here, president is neither being used as a title before a person’s name, nor as a direct address, so it isn’t capitalized."
