I think you better rethink that as being an objective of the Democrats. What do they gain by doing so? Nothing that I can come up with it. It doesn't help them in the midterms, or with controlling the Supreme Court.
Read what I posted.
Once Kavanaugh is confirmed, they spend the next six weeks waging a "Fight the GOP War on Women" campaign, with Buzzy Ford as one of their leading media stars.
They can't do this as long as she is a potential witness before the U.S. Senate Judiciary Committee.
