I've thought from day one that, once Q was publically acknowledged and mainstreamed, that would be the derp's strategy. All they have to do is ask the question to get that ball rolling.
And yet they don't. Why?
Because to acknowledge Q and try the 'leak' strategy, is to admit and discuss ALL the information that Q has 'leaked'.
They are deathly afraid of THAT conversation. And so they ignore Q and turn it into a LARP and/or white natianolist conspiracy theory, etc. Hell, some even say Q is a black hat op. *looking at you, edible root*.
And in the meantime, the information flows.
The classified info leak via Q is admittedly a tougher sell because of the need for technical explanations that will fly over the heads of a great preponderance of their LIVs.
I think it's still a toss-up whether Pelosi will get any Articles of Impeachment passed. With Nunes' minority hearings requirement, I doubt she'll be able to accomplish that vote before Horowitz's report breaks onto the interested public, after which it'll be quite clear that President Trump will overwhelmingly win 2020, creaming any Dem contender even worse than if their name were "Walter Mondale." Coattail-seeking House reps won't want PDJT to seem have a mandate that wields a highly visible cudgel against those that voted for impeachment.
