That is a perfect example of thermostatic opinion.

那是一个典型温差意见例子。

And in a world like that, little thermostatic swings are very important.

在一个这样世界里， thermostat-like 波非常重要。 注：这里 " thermostat-like" 是指像恒温器一样，即公共意见波。但由于直接翻译“thermostatic swings”为“恒温器波”可能不够自然，可以根据具体语境达方式。此处为了忠实于原文，保留了“thermostatic”，但实际应用中可以进一步优化为“民意波”。

In a world where you have thermostatic change and every election is very close, you tend to have elections swinging back and forth.

在一个变化如恒温节般妙且每次选举都势均力敌世界里，你往往会看到选举结果来回摇摆。
