Personally, I'd recommend approval voting.
The candidate with the most approval of the party wins. That would tend to be the most unifying of the candidates.
I would agree with something like that. Only getting to choose one candidate in a multi-candidate election means that one wing of the party can split the vote and make the least-preferred candidate come out the winner. If you run 4 Ted Cruz clones who each get 19% of the vote and a Romneybot gets 24% of the vote, the Romneybot wins, even though 76%, the vast majority of the voters would’ve ranked him last choice on their list. A multi-candidate election where you can only pick one name is an utterly stupid, meaningless and counterproductive exercise.
