Mr. A will always prefer you over me on his campaign 😉
Mr. A can prefer all he wants, I'm with Mr. D. and Miss F

I don't see it's a bad idea too. The only problem last two years we had were the merit sent by users and accounts (those were voting) were taking advantages from it.
For the record, I don't think it's necessary to adjust "voting power" based on anything else than "one user, one vote".
