This question:
Who would you rather be elected?
may elicit the following answer (not sure if it's grammatically correct):
I'd rather have A win
but supposing that the elections are already over and we have a president elect, if I were talking with a friend and wanted to ask him who he thinks should've been elected using a rather construction, how should I formulate the question? Is it right if I say "Who would you rather had been elected"?

For this, we need to use the "conditional" imperfect with the past participle.
Please note it would also sound more natural if you replace the word prefer to the verb to 'prefer' now. So:
"I would have preferred it if he had won."
