In Trip to Ha Noi, Susan Sontag writes about Vietnam electoral system and it’s potitical parties.

"But Lao Dong, the Workers Party, with nearly a hundred members on its Central Committee, is "the Party"; it runs the country, and the candidates it proposes are overwhelmingly .) But the preference for government by a single party of newly independent countries which have never known multi-party democracy is a fact that merits a more discriminating response than automatic disapproval."

Please tell me which option below is correct:

(1): The electoral system treats it’s candidates better than other’s
(2) The electoral system only likes it's candidates
(3): Most of people the electoral system selected are it’s candidates

Thanks!

We don’t have enough information to be able to say in what way the electoral system gives preference to candidates from Lao Dong. Your #3 is certainly correct.

(All of the apostrophes in your sentences should be omitted, by the way.)
