I'd say its not even a completely liberal thing to do, but they are indeed more likely to make these sort of studious claims in this time. they are trying to explain what they see as absurd, imagine how alienating it must be to be in the echochamber. to be told your going to win the election, then a orange man with good honest humor who is supported by a cartoon frog wins the vote. Yes, that is quite insane but only because they can't point to themselves and blame themselves for this result and they can't admit the key mistake of going with Hillary. You are completely right that they do have a mechanism to work by, and I believe they are aware of it but know that there really isn't any way to speak outside of this system, as doing so likely risks you being alienated by the last few that are still human to them.
