Some criticized her as a fence sitter, waiting to see which way the wind would blow.

有些人批评她是事态的观望者，总是静观风向而不做明确的决定。

" To be a fence sitter" would be to be someone who doesn't want to make anyone angry, so they don't make a decision or they don't choose one side versus the other.

“做一个围栏保姆”就是不想让任何人生气，所以他们不会做出决定，也不会选择一方与另一方。
