Theory: Why is Judge Kavanaugh so important to be confirmed quickly?

On the surface, it is believed it will tip the court to a reliable conservative vote and that cannot stand (Roe v. Wade) in the liberal view. But I am not sure that is true. I think the importance is more immediate. So far, we can conclude that Congress is corrupt. We also can reasonably assume the executive branch is corrupt (DOJ/FBI/CIA, etc). But no allegations have been made on the Judiciary. What if the release of the FISA docs do "Bring down the house?" What if the corruption is also rampant in the FISC system? Who is in charge of FISC? Would he then be removed/recused? If so, then the current court switches to a 4-3 liberal majority. Hard to prosecute in that environment. This would explain the urgency, and the FISA release delay.

Not sure if it has been brought up before, but this is the only puzzle piece that fits in my mind….going back to lurking now.
