Vote no or go to jail.
Only way to win is not to vote.
Regardless of the result of the referendum, it will have absolutely no credibility.
“Only way to win is not to vote.”
Except that is unlikely as vote collectors with armed Russian soldiers are going house to house, door to door and demanding that people open up and vote, fill out the ballot, and unfolded hand it to the vote collector. I saw at the polling station an unfolded ballot was put in a transparent box where you could read the ballot leaning against the box wall.
