A one week delay is fair. It would have looked really bad for the GOP if they had gone through with the vote without at least that, though I wouldn't expect any more.
This whole thing has been a shitshow. Unless the FBI finds something noteworthy, it's likely Kavanaugh gets voted through at the end of the week. But there likely won't be any findings that prove his innocence or guilt (what could they really find?), so you're going to have a body of people who are sure of his guilt, and another body that is sure of his innocence and how it was some political smear job, which I guess would Brett Kavanaugh the new Clarence Thomas. I wonder if allegations of this nature are going to become more or less common?
