In regards to the WHY i think i know why they are trying so hard right now to get potus to denounce Q. If you think about it, Trump confirming Q right now before the election would give the media a huge point of attack which would be that he is trying to benefit from the Q movement by confirming now before the election. If trump wins the election and confirms sometime after that point then they can no longer use that excuse to make trump look bad, and then trumps word has that much more weight since he waited to win the election first.
yea i mean if they somehow got him to confirm before the election it would basically render the confirmation as an attempt to get more votes for the election. people wouldnt be able to take him seriously because of how it looks. but allot of people will likely believe him if he wins the election and then at some point confirms then.
