An excellent point, and you have excellent questions. My only response that I can think of is that these people have gotten away with what they have gotten away with for years. So they believe that since they have gotten away with it in the past, there has to be an out for them. They actually believe that.
Q has already said that the media was ready to pounce if there are videos and pictures released, by claiming that new computer software can fake anything. Thats in a post by Q.
All the rest, they are putting all their eggs into one basket. Winning the midterms and impeaching Trump. They also always have their reliable mockingbird media. They are using the weapons that they have. And its going to be a bloody, bloody fight.

I think they will fight to the bitter end; not because they really think they can win, or that they will not be exposed; maybe some are stupid/drugged enough to be in that illusion. IMHO they are just crazed and evil and will be dragged screaming and clawing and writhing off the stage frothing about Drumpf and “I din’t do nuffin”.
They are the very opposite of rational. And they are driven.
