"I frankly don’t understand why people are still wondering if there was collusion during the campaign."
Digby, none of these people you are referring to are "wondering if there was collusion during the campaign." They all know perfectly well that there was collusion- massive, treasonous collusion, as proven beyond a shadow of a doubt through dozens of actions by Donald Trump and his minions. They are not questioning the clear facts, as you very well know. They are attempting to shout those facts down in any way they can, by denying over and over again what we all know to be true.
They are not stupid; they are paid liars, and they are going to go on lying, and threatening, and diverting people's attention, from now until doomsday, since the alternative is to admit that their entire party is a corrupt pack of traitors.
There. Isn't it nice to just state the truth for once?
