If anybody will ask me I would prefer the need for a speech to be counted as a candidate. No speech, no candidature. An NT coach must be able to speak with users, so a speech is a way to show that he is able. Besides this, he put information about him too.
Perhaps an approach would be to have the candidate put in his speech
when he candidates himself?
And lock that information once the election starts?
That way, along with all the information you were referring to, the voter would also see the election speech. Obviously, if the speech is "vote for me" or "sdfgdfgw", it won't look great for his candidacy.
