be (all) over bar the shouting idiom UK
基本已成定局
If an activity is all over bar the shouting, the result of it is known, but it has not been officially finished or announced, so people can still say that a different result is possible.
With practically all the results declared, the Nationalist Party has 68 percent of the vote, so it's all over bar the shouting. 几乎所有的结果已宣布,国民党赢得了68%的选票,看来选举结果已成定局。
