@Bloodybridget - sadly, it looks like what started as a joke has developed into a fake news story.
There was no poll. Time Magazine chose Musk as Person of the Year. The Guardian frequently do "Tell us" requests for readers' views, which they might later weave into an article quoting some of the best responses. They chose to ask people to submit their ideas for who they would have picked for PotY and their reasons. They've now closed the submission form (some are making fun of the fact it says "form deactivated" on the webpage - but some are genuinely buying it as some kind of conspiracy. Actually, you can find other "Tell us" articles where the form has been deactivated even for non-controversial topics such as "favourite spaghetti recipe").
The journos at the Guardian now need to decide what to do with the responses. They might decide to ignore all the JKR responses (that wouldn't come as too much surprise for the Guardian), but it's going too far to suggest they are pulling a poll because JKR "won".
