这个句子中的were she 有语法问题吗

这个句子中的were she 有语法题吗？ situation is a little better for Hillary Clinton were she to win the nomination
这个句子的后半个部分对吗？怎么有个were she呢？   

参考案 这是常见的用法, Were she 是虚拟倒置, 也可将句子改为:

situation is a little better for Hillary Clinton if she were to win the nomination

如果得到(共和党内总统)提名(还没有呢, 所以用虚拟), 希拉里的情况(或形势)就会好一点.

其他回   好怪的结构。要是我来写：
Situation is a little better for Hillary Clintor for her to win the nomination.
