About the communist, not hard to believe the high-number with them, governed for most of Moldova's independence and controversial change of government that "ousted" them that lead to this referendum (probably we can add a "background" section).The main point being that was an intent once upon a time and they signaled it, so in some capacity a major party's call like this is certainly warranted in mention.
For the quote, i agree the second sentence can go, the only reason i had to keep it was the indication of the 33%threshold, but we can reword it outside the quote if you feel so. (there was no other mention of the requirement with sources (the template though had it)
Perhaps an analysis is found in Moldova? Can you get one? I cant read it. then we can discuss the wording if need be
