First, for this to be an equilibrium,

第一点如果这是一个均衡
it better be the case that they're symmetric on left and right.

那么这两个候选人必定是左右对称的
If they're not symmetric, then it isn't an equilibrium,

如果不对称就不可能是均衡
because one of those candidates is going to lose for sure

因为不对称必然有一个参选人会输掉选举
and the way we set up the model that means that

在我们这个模型中这就意味着
one of them will drop out: they will deviate to drop out.

两个参选人中会有一个退出选举
Is that correct? Let's also illustrate this.

是这样吧我们还说过
So,we've already illustrated that

我刚才说过了
they're not particularly close to the center.

他们未必都集中在中间立场上
Let's illustrate what I meant by

我来解释一下为什么我说
somebody on the left causing the right wing to win.

左派有新候选人加入导致右派胜利
So, if this was the election,

假如这是一次选举
