I'm not sure if splitting the lists between elected and unelected candidates is such a good idea. Because, essentially, the post view is a digital representation of the ballot paper, and the ballot paper - probably - should be reproduced as accurately as possible, even after the election has come to a close. I'd opt for repeating the winners compactly under the new 'Elected candidates' heading and restoring the complete list below under 'All candidates'.
