Democrats are pressing her to recuse herself should she be seated given that

这里用should she be seated 是虚拟语气吗？

你的问题应该换一个问法：should she be seated是真实条件还是非真实条件。

答案是：依据主句谓语动词形式，这个条件是真实条件句。

should do用在if从句中，既能够表示非真实条件，也可以表示真实条件，不同就是主句的谓语动词形式。主句用陈述语气，should do表示的就是真实条件；主句谓语动词用虚拟语气，should do表示的就是非真实条件。无论should do表示的是真实条件还是非真实条件，都可以省略if 而将should倒装。
